Answer 1

Question :-

There are two cuboidal boxes as shown in the figure. Which box requires the lesser amount of material to make?

Given :-

• Length of cuboid = 60m

• Breadth of cuboid = 40m

• height of cuboid = 50m

__________

• side of cube = 50m

To find :-

• Which box requires the lesser amount of material to make?

Formula used :-

For cuboid

$=\: \: \: \: \: \: \: \: (l \times b \times h)$

For cube

$= \: \: \: \: \: \: \: \: ( {side)}^{2}$

Solution :-

(a) Volume of the cuboid

= l × b × h = 60 × 40 × 50

= 120000 ${cm}^{2}$

___________

(b) Volume of cube

= ${(side)}^{3}$

= ${(50)}^{3}$

= 50 × 50 × 50

= 125000 ${cm}^{2}$

Cuboidal box (a) requires lesser amount of material
