Question

Jamie just bought two boxes. the first box is square, with each side measuring 10 units, and is 4 units high. the second box is rectangular and has twice the volume of the square box. if the height of the second box is 5 units, and the width is 10 units, what is the length of the second box?

Answer 1

16 units is your Answer

Answer 2

16 units is the length.

Explanation:

To solve this we first have to calclate the volume of th square box:

10 units * 10 units * 4 units= 400 units^3

The volume of the square box is 400 cubic units, if the rectangle box you know that it has double the volume: 400*2= 800 cubic units.

So we just have to clear the formula of the volume for length:

Volume= Lenght * Width * Height

Volume= Length * 5 units * 10 units

800/ 50 square units= Length

Length= 16 units.
