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



Surface area of cube=6 x side^2
Here, cube is without lid. So surface area=5 x side^2

5 x side^2=180
side^2 = 180/5
side^2 = 36
side = \sqrt{36}
side =6 cm

Ans: Dimensions: 6cm x 6cm x 6cm
Hope that helps you :) A good piece of advice would be to erite it down first so that you understand it better.
