To find out how much room is left in the corridor, we need to calculate the volume of both the corridor and the container and then subtract the volume of the container from the volume of the corridor. The volume of the corridor can be calculated using the formula: Volume = Length × Width × Height. Plugging in the given measurements, we get: Volume of corridor = 6 feet × 5 feet × 8 feet = 240 cubic feet. Similarly, the volume of the container can be calculated using the same formula: Volume of container = Length × Width × Height. Plugging in the given measurements, we get: Volume of container = 3 feet × 2 feet × 4 feet = 24 cubic feet. To find the room left in the corridor, we subtract the volume of the container from the volume of the corridor: Room left = Volume of corridor - Volume of container = 240 cubic feet - 24 cubic feet = 216 cubic feet. Therefore, there is 216 cubic feet of room left in the corridor.
Question 2
To find the volume of soil removed from each planting pit, we need to multiply the length, width, and depth of the pit. The length of the pit is 2 inches, the width is 4 inches, and the depth is 6 inches. Therefore, the volume of soil removed from each pit is calculated as follows: Volume = length * width * depth = 2 * 4 * 6 = 48 cubic inches.
Question 3
To determine the total volume of the two cisterns, we need to calculate the volume of each cistern and then add them together. Each cistern has a length of 6 m, a width of 4 m, and a height of 8 m. To find the volume of one cistern, we multiply these values: 6 m * 4 m * 8 m = 192 cubic meters. Since there are two cisterns, we multiply the volume of one cistern by 2: 192 cubic meters * 2 = 384 cubic meters. Therefore, the total volume of the two cisterns is 384 cubic meters.
Question 4
Step 1: Write the equation for the total cost: 19 + 4x = 90. Step 2: Simplify the equation by subtracting 19 from both sides: 4x = 71. Step 3: Solve for x by dividing both sides by 4: x = 17.75. Therefore, Jill paid $17.75 for each set of headphones.
Question 5
To find the volume of the box, multiply its width, depth, and height. The formula for the volume of a rectangular prism is V = length * width * height. In this case, the width of the box is 4 feet, the depth is 5 feet, and the height is 2 feet. Therefore, the volume of the box is V = 4 ft * 5 ft * 2 ft = 40 cubic feet.
Question 6
Number of screens that were open = 16 - w
Question 7
Step 1: Write the equation for the total cost: 45 + 4x = 100. Step 2: Simplify the equation by subtracting 45 from both sides: 4x = 55. Step 3: Solve for x by dividing both sides by 4: x = 13.75. Therefore, Mandy paid $13.75 for each set of headphones.
Question 8
6 - q
Question 9
1. Let's represent the number of balloons in each pack by x. 2. Randy bought 7 packs of balloons, so the total number of balloons he has is 7x. 3. We know that there are 42 balloons in total, so we can set up an equation: 7x = 42 4. To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides by 7: x = 6. 5. Therefore, each pack of balloons comes with 6 balloons.
Question 10
The volume of the box is calculated by multiplying its length, width, and height. Therefore, the volume of the box is 2 * 2 * 4 = 16 cubic meters.
Question 11
Number of aisles that were open = 7 - v
Question 12
To find the volume of shampoo Andrew bought, we need to calculate the volume of each box and then multiply it by the number of boxes. For each box of shampoo: Length = 7 cm Width = 8 cm Height = 5 cm Volume of each box = Length × Width × Height Volume of each box = 7 cm × 8 cm × 5 cm Volume of each box = 280 cm³ Volume of 9 boxes of shampoo = Volume of each box × 9 Volume of 9 boxes of shampoo = 280 cm³ × 9 Volume of 9 boxes of shampoo = 2520 cm³
Question 13
To find the volume of water used to fill the swimming pool up to 4 ft deep, we need to calculate the volume of a rectangular prism.
The formula for the volume of a rectangular prism is V = l * w * h, where V is the volume, l is the length, w is the width, and h is the height.
In this case, the length (l) of the pool is 25 ft, the width (w) is 18 ft, and the height (h) is 4 ft (since Alex filled the pool up to 4 ft deep).
Substituting these values into the formula, we have:
V = 25 ft * 18 ft * 4 ft
Calculating the multiplication:
V = 450 ft² * 4 ft
V = 1800 ft³
Therefore, the volume of water used to fill the swimming pool up to 4 ft deep is 1800 cubic feet.
Question 14
1. Let's represent the number of balloons in each pack by x. 2. Laura bought 8 packs of balloons, so the total number of balloons she has is 8x. 3. We know that there are 48 balloons in total, so we can set up an equation: 8x = 48 4. To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides by 8: x = 6. 5. Therefore, each pack of balloons comes with 6 balloons.
Question 15
The volume of space under the television stand is a rectangular prism. The width, length, and height of the prism are 2.5 feet, 8 feet, and 4 feet, respectively. Therefore, the volume of space under the television stand is 2.5 x 8 x 4 = 80 cubic feet.
Question 16
The volume of the box is calculated by multiplying its length, width, and height. Therefore, the volume of the box is 2 * 2 * 4 = 16 cubic meters.
Question 17
To find the volume of the box, we multiply its length, width, and height: 12 cm × 1 cm × 15 cm = 180 cm³. To find the volume of the basket, we multiply its length, width, and height: 27 cm × 5 cm × 18 cm = 2430 cm³. To find the space left in the basket, we subtract the volume of the box from the volume of the basket: 2430 cm³ − 180 cm³ = 2250 cm³. Therefore, there is 2250 cm³ of space left in the basket.
