Hlo friend.. Cutiepie Here..

Here is ur answer :

First, the formula used in this question :

Lateral surface area of cuboid :

$2(length + breadth)height$

Now come to the question,

A match box is opened at both of its end sides.

Its means we have to find the areas of four sides or Lateral surface area.

Length l of matchbox = 5 cm

Breadth b of matchbox = 3.5 cm

Height h of matchbox = 1.5 cm

Area of paper used to make:

= 2 ( l + b ) h

= 2 ( 5 + 3.5) 1.5

= 2 ( 8.5) 1. 5

= 25.5 cm²
