Question

the length breadth and height of a cuboidal box are 20cm 15 cm and 12 cm find total surface area​

Answer 1

mark me as brain list. follow me for mathematical problems.

Answer 2

length of a cuboid = 20cm

breadth of a cuboid = 15 CM

height of a cuboid = 12cm

$2 \times (lb + bh + hl)$

so

2 * (20*15 + 15*12 + 12* 20)

2 * ( 300+180+240)

2 * 720

the total surface area of the cuboid

1440cmsquare
