Question

Kim wants to fill a cubical fish tank with water. If the side of the tank is 10 ft, how much water will be required to completely fill the tank?

• A. 100 square feet
• B. 100 cubic feet
• C. 100 square feet
• D. 1,000 cubic feet

Answer 1

The correct option is D 1,000 cubic feet

Given,
Length of the cube = 10 ft

Volume of a cube is: $\text{length}\times \text{width}\times \text{height}$

For a cube,
Length = Width = Height

$\therefore$ Volume of the cube = 10 x 10 x 10
= 1000
So, the volume of the water required to fill the tank completely is 1,000 cubic feet.
