Question

three cubes each of volume 216cm cube are joined end to end . Find the surface area of the resulting cuboid.​

Answer 1

Answer:

504cm²

Step-by-step explanation:

Volume of cube=a³

216=a³

a=6 cm

now,

sides of resulting cuboid are length is 6+6+6=18 cm

breadth is 6 cm

and

height is also 6 cm

therefore

S. A. of resulting cuboid is [2(lb+bh+hl)]

=2(18*6+6*6+6*18)

=2(108+36+108)

=2(252)

=504cm ²

Answer 2

Answer:

504 cm^3

Step-by-step explanation:

volume of 1 cube =216

volume =a^3

a^3=216

a=6 cm

Edge of one cube=6 cm

Then 3 cubes=6+6+6 cm

=18 cm

BREADTH=6 cm

HEIGHT=6 cm

T.S.A=2(lb+bh+hl)

2(108+36+108)

=2(252)

=504 cm^3
