Question

a cuboidal box has edge 10 cm and the cuboidal box has dimension 12.5 *10cm*8cm . which box has greater lateral surface and by how much

Answer 1

Answer:area of cube is greater by 40 cm

Step-by-step explanation:

Area of square = s * s

So, 10*10 = 100 cm sq.

Lateral surface area = 4 * a

So, 4 * 100 = 400

Lateral surface Area of cuboid= 2 ( l + b ) h

2 ( 12.5 + 10 ) 8

(25+ 20 ) 8

200 + 160 = 360 cm sq.

Hence, area of cube is greater by 40 cm
