Question

A box is in the shape of a cube with side 25 metres.

Also , there is a box in the shape of cuboid with dimensions 20 cm x 25 cm x 18 cm

Which box has
a) Greater capacity
b) Greater T.S.A

Answer 1

hey there .

side of cube = 25 m

so volume of cube = ( side) ^3

= (25)^3 =

= 15625 m^3

◆ dimension of cuboid =20cm ×25cm×18 cm

volume = l×b×h
= 20 × 25×18

=9000cm^3
here we can see that cuboid has volume less so it has less capacity than cube.

now.

TSA of cube = 6a^2

= 6 × (25)^2

=3750 m^2

TSA of cuboid = 2(lb+bh+hl)

= 2(500+450 +360)

= 2620 cm^2

from above we can see that TSA of cube is more.
