Question

The outer surface of a jewellery box is to be covered with a velvet cloth. If the box is 2 m long,1 m wide and 1.5 m in height, Find how much cloth will be required

Answer 1

Answer:

Cloth required to cover the box is 13 m^2

Step-by-step explanation:

outer surface means total surface area

and the jewellery box is cuboid in shape

Surface area of cuboid = 2( lb + bh + hl ) sq. units

here l = length , b = breadth , h = height

for the question : l = 2m , b = 1m , h = 1.5 m

S.A of jewellery box = cloth required

= 2( 2+ 1.5 + 3)

= 2( 6.5 )

= 13.0 sq. m

Answer 2

13 sq.m
