The volume of a rectangular prism can be calculated with the formula V=lwh, where V is the volume, l is the length, w is the width, and h is the height. If a rectangular prism has a volume of 90 ft.3, length of 3 ft., and height of 12 ft., what is its width? Enter your answer as a decimal.(1 point)
To find the width of the rectangular prism, we can rearrange the formula V = lwh to solve for w:
w = V / (lh)
Substituting the given values into the equation:
w = 90 ft^3 / (3 ft * 12 ft)
w = 90 ft^3 / 36 ft^2
w ≈ 2.5 ft.
Therefore, the width of the rectangular prism is approximately 2.5 ft.
To find the width of the rectangular prism, we can rearrange the formula for volume (V=lwh) to solve for the width (w).
The formula becomes:
w = V / (lh)
Given:
V = 90 ft^3
l = 3 ft
h = 12 ft
Substituting these values into the formula, we have:
w = 90 ft^3 / (3 ft * 12 ft)
Calculating:
w = 90 ft^3 / 36 ft^2
Simplifying:
w = 2.5 ft
Therefore, the width of the rectangular prism is 2.5 ft.
