Question

5 cubes each of volume 1728 m^3 are joined end to end .find the Csa of the resulting cuboid.​

Answer 1

Answer:

Volume of each cube=1728cm³

a³=12³

→a=12

side of each cube =12cm

if we join5 such cubes end to end,

length=12+12+12+12+12=60cm

breadth=12cm

height=12cm

Lateral surface area of resulting cuboid=2h(l+b)

=2(12)[60+12]

=24×72

=1728cm²
