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?
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.
