✩ 4.0

Volume of the cuboid

= length*breadth*height

= 7*5*4

= 140 cm³

Now,

Volume of cube

= (side)³

= (6)³

= 216 cm³

Therefore

The volume of cube is greater than the volume of cuboid

by 216 cm³- 140 cm³ = 76 cm³

Answer 2

Answer:

166cm³

Step-by-step explanation:

volume of a rectangular box (cuboid)=2(lb+bh+hl)

putting the values of the b , h and l

b=7 cm

h=4 cm

l=5 cm

2(5×7+7×4+4×5)

2(35+28+20)

2(55+28)

2(83)

2×83

166 cm³

volume has a 3rd dimensional unit because it has 3 dimensions (l , b and h) so it has 3 power on its

unit.
