Question

Suman made a cardboard box in the form of a cube without lid if the total surface area of this box was 180 square cm what are the dimensions of the box​

Answer 1

6cm

The dimensions are 6cm x 6cm x 6cm

Explanation:

Surface area of a cube = 6a²

where a = edge

but because this cube isn't covered, the sides would by 5 and not 6

5a² = 180cm²

divide both sides by 5

a² = 36cm²

Find the square root of each side

a = 6cm

The dimensions are 6cm x 6cm x 6cm
