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 need to use the formula for the volume of a right rectangular prism:
Volume = Length x width x height.
Given that the volume is 1,920 cubic inches, the height is 12 inches, and the length is 20 inches, we can substitute these values into the formula:
1,920 = 20 x width x 12
To find the width, we divide both sides of the equation by 20 x 12:
1,920 ÷ (20 x 12) = width
Simplifying the denominator:
1,920 ÷ 240 = width
The result is:
8 = width
Therefore, the width of the tank is 8 inches.
To find the width of the fish tank, we can use the formula for the volume of a rectangular prism.
Volume = length × width × height
Given:
Volume = 1,920 cubic inches
Height = 12 inches
Length = 20 inches
Substituting the given values into the formula, we have:
1,920 = 20 × width × 12
Now we can solve for the width:
1,920 = 240 × width
Divide both sides of the equation by 240:
1,920 ÷ 240 = width
Simplifying:
8 = width
Therefore, the width of the fish tank is 8 inches.
