Answer 2

Length of the box, l = 20 cm

Breadth of the box, b = 12 cm

Height of the box, h=10 cm

∴ Surface area of the vertical faces of the box

=2 (l+b) ×h

=2(20+12)×10

=2×32×10

=640 cm²

Also,

Total surface area of the box

=2(lb+bh+hl)

=2(20×12+12×10+10×20)

=2(240+120+200)

=2×560

=1120 cm²

Thus, the surface area of vertical faces and total surface area of the box is 640 cm²

and 1120 cm²
