Question

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

Answer 1

Answer:

Box (a)

Step-by-step explanation:

Volume of A = $lbh$ = 60 × 40 × 50 = 120000cm³

Volume of B = $lbh$ = 50 × 50 × 50 = 125000cm³

⇒ 120000cm³ < 125000cm³

⇒ Therefore, box A has a lesser volume and thus will require less material to make.
