Answer 2

You just said that the box has a square base, therefore 'the length of a side of the base of the box' would also be 8cm.

If however you were referring to the height of the box, then

Step 1: Give the height a variable name
let height = h

Step 2: Write down the formula used to figure out the surface area of a regular cuboid
\[2\times base ^{2}+4\times (base \times height)\]

Step 3: Enter all the known values
\[2\times 8 ^{2}+4\times (8 times h)=264\]

Step 4: Solve for h
