Question

a match box is opened at both its end sides. Find the area of paper used to make if its length, breadth and height are 5cm,3.5cm and 1.5cm respectively.​

Answer 1

Answer:

First, the formula used in this question :

Lateral surface area of cuboid :

2(length + breadth)height2(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

Answer 2

Step-by-step explanation:

2(length + breadth

We have to find the lateral surface area of cuboid

L=5 cm

B=3.5 cm

2(l+b) h

2( 5+3.5)1.5

2(8.5)1.5

25.5 cm2
