respectively. Find the area of canvas required to cover this box.

Answer 1

Given:

• The length (l) of a cuboidal box = 2m 10cm

= 200 cm + 10 cm

= 210cm

• The breadth (b) of the cuboidal box = 1m

= 100 cm

• The height (h) of the cuboidal box = 80 cm

To find:

The area of the canvas required to cover the box.

So,

We have to find the Total Surface Area (TSA) of the cuboidal box

• The formula used to find the Total Surface Area of a cuboid is

= 2(lb+bh+hl) unit sq.

= 2[ (210*100) + (100*80) + (80*210) ]

= 2[ (21000) + (8000) + (16800)]

= 2*( 45800 )

= 91600 cm sq.

Hence

The cuboidal box required 91600 cm sq. canvas to cover fully.
