a fish tank in the shape of a right rectangular prism has a volume of 1,920 cubic inches. What is the width of the tank if the height is 12 inches and the length is 20 inches?

1 answer

To find the width of the tank, we can use the formula for the volume of a rectangular prism: V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

Given:
V = 1920 cubic inches
l = 20 inches
h = 12 inches

Plugging in these values into the formula, we get:
1920 = 20w * 12

To solve for w, we divide both sides of the equation by 20 * 12:
w = 1920 / (20 * 12)

Evaluating the expression on the right side:
w = 1920 / 240
w = 8

Therefore, the width of the tank is 8 inches.
