Question

A cube has a surface area of 3,750 square feet.

Find the length of one side.

Answer 1

Surface area of a cube =
`6a^2`

So 3,750 =
`6a^2`

We need to find the value for


Eliminate 6 from both sides using division


`3750/6 = 6a^2/6 625 = a^2`

Now we have the area of one side of the square since the area of a square equal
`a^2`

Square root
`25` and you get one side of the square.


`√(625)` =
