Q. 19

# The dimensions of

Answer :

Given,

Ratio of dimensions of rectangular box = 2:3:4

Let length of box = 2x m

Let breadth = 3x m

Let height = 4x m

Area of sheet of paper required for covering it = total surface area of cuboid

=

Cost of covering it with sheet of paper at Rs.9.50 /m^{2}=

Cost of covering it with sheet of paper at rate Rs.8/m^{2} =

=

=

=

=

So,

Length of box = 2x = 2×4 = 8 m

Breadth of box = 3x = 3×4 = 12 m

Height of box = 4x = 4×4 = 16 m
