The formula for the volume of a rectangular prism is V = lwh, where V represents the volume, l represents the length, w represents the width, and h represents the height.
In this case, the volume is given as 50 cubic units and the height is given as 2, so the formula becomes:
50 = lw(2)
To find the area of the base, we can isolate the l and w by dividing both sides of the equation by 2:
25 = lw
Therefore, the area of the base is 25 square units.
The correct answer is 25.
The formula for the volume of a rectangular prism is V = lwh, where V represents the volume, l represents the length, w represents the width, and h represents the height.
In this case, the volume is given as 1000 cubic units, the height is given as 10, and the length is given as 20, so the formula becomes:
1000 = 20w(10)
To find the width, we can isolate w by dividing both sides of the equation by 200:
5 = w
Therefore, the width is 5 units.
The correct answer is 5.
To find the area of the base of a rectangular prism, we need to use the formula for the volume, which is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
In this case, the volume is given as 50 and the height is given as 4. So the formula becomes:
50 = lw(4)
To find the area of the base, we need to isolate the variables l and w. Dividing both sides of the equation by 4, we get:
12.5 = lw
Therefore, the area of the base is 12.5 square units.
The correct answer is 12.5.
To find the width of a rectangular prism, we can use the formula for the volume, which is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
In this case, the volume is given as 162,000, the height is given as 40, and the length is given as 90. So the formula becomes:
162,000 = 90w(40)
To find the width, we need to isolate the variable w. Dividing both sides of the equation by (90)(40), we get:
w = 162,000 / (90)(40)
w ≈ 45
Therefore, the width of the rectangular prism is approximately 45 units.
The correct answer is 45.
To find the volume of a rectangular prism, we can use the formula V = lwh, where V represents the volume, l represents the length, w represents the width, and h represents the height.
In this case, the length is 7.5, the width is 5, and the height is 3. Substituting these values into the formula, we get:
V = (7.5)(5)(3)
V = 112.5
Therefore, the volume of the rectangular prism is 112.5 cubic units.
The volume of a right rectangular prism is 1000, the height is 10, and the length is 20. What is the width?
