Question

Area of sheet for making box

Answer 1

We have been given length of matchbox 1.5 m
Breadth= 1.25m
Height = 0.65m

We know that area of four walls or CSA of cuboid is
$2(l + b) \times h$
And we have also to cover Bottom so total area is
$2(l + b) \times h + l \times b$
So
$2(1.5 + 1.25) \times 0.65 + 1.5 \times 1.25$
$= 5.45 {m}^{2}$
