Answer 2

Answer:

7 papers are required.

Step-by-step explanation:

To find the total number of paper required need to put the values in below mentioned formula:

First is used to find out the surface area of the box = 2(lb + BH + HL)

Second formula is used to area of paper=$side^{2}$

Given:    The length is 80cm,  breath is 40cm and  height is 20cm.

To find: Need to calculate the total number of papers are required.

Calculation:

Find out the surface area of the box = 2(lb + BH + HL)

=2(80×40+ 40×20+20×80)

=2(5600)

=$11200cm^{2}$

Area of paper=$side^{2}$

$=40^{2}\\ =1600cm^{2}$

Paper required: $=\frac{11200}{1600}$

=7 papers

So, the 7 papers are required.
