Question

A cube box has edges that are 18 cm long. The box does not have a top. What is the surface area of the box? Justify your answer pls

Answer 1

A cube has 6 sides, but since this one doesn't have a top, we'll have to work with 5 sides.

S.A. = Area of 1 side × 5

= 18 × 18 × 5

= 1620 cm^2
