Question

The following geometrical shapes are made up of paper. ___ requires the least amount of paper.

Answer 1

Calculating Surface Area

Surface Area of Cube = 6$a^2$= 6 $\times$ 4 $\times$ 4 = 96 $c{m}^2$

Surface Area of Cuboid = 2(lb + bh + hl) = 2(10 $\times$ 5 + 5 $\times$ 2 + 2 $\times$ 10) = 2 $\times$ 80 =160 $c{m}^2$

Least Surface Area = Cube = 96$c{m}^2$ (cube)
