Answer 2

The answer is

${900cm}^{2}$

Length of cuboid = 15cm

Breadth of the cuboid = 12cm

Height of cuboid = 10cm

Surface area of a cuboid = 2(lb + bh + hl)

$2(15 \times 12 + 12 \times 10 + 10 \times 15) {cm}^{2} \: \: \: \: \: so \: 2(180 + 120 + 150) {cm}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: the \: next step \: is \: 2(450) {cm}^{2} = 900 {cm}^{2}$
