Question

A cuboidal box of dimensions 16 cm x 12 cm x 5 cm is to be gift wrapped using a colour paper.
Find the area of the colour paper required to completely cover the cuboidal box. Assume that
there is no wastage of paper in this process.
​

Answer 1

area required=total surface areaf cubiod

======[2(16×12+12×5+5×16)

total surface area=2(192+60+80)

=2×332

=664cm^2

ok

Answer 2

Answer:

Area of colour paper required to completely cover the cuboidal box is 664 cm²

Step-by-step explanation:

Given:-

• A cuboidal box having dimensions 16 cm, 12 cm and 5 cm is wrapped around a gift using coloured papers.
• During that wrapping, he/she wastes no paper.

Find:-

Area of the colour paper required to wrap around the gift.

Solution:-

We have given that dimensions of the cuboidal box -

• length (l) = 16 cm
• breadth (b) = 12 cm
• height (h) = 5 cm

Now,

The gift that is wrapped using colourful papers is cuboidal in shape. And we have to find the area of the coloured paper required to wrap that gift.

Means, we have to find the total surface area of the cuboidal box.

Total surface area of cuboid = Total surface area of the cuboidal box.

Total surface area of cuboidal box = 2(lb + bh + hl)

Substitute the known values above.

=> $\sf{2(16\:\times\:12\:+\:12\:\times\:5\:+\:5\:\times\:16)}$

=> $\sf{2(192\:+\:60\:+\:80)}$

=> $\sf{2(332)}$

=> $\sf{\bold{664\:cm^2}}$
