Question

The length breadth and height of a
room are 5 cm am and 3m resp.
find the total surface area
and lateral surface area of
the

room.
a) 60m² 45m
b) 45m, gucm

c) gum, 45 m²
d) 45m, 45m​

Answer 1

Answer:

Given,

Length of room = 5 m

Breadth of room = 4 m

Height of room = 3 m

Then,

We know that room is Cuboidal in shape. And,

Lateral surface of cuboid = 2(l + b)×h =

= 2(5 + 4)×3

= 18 × 3

= 54 m^2

Also,

Total surface of cuboid = 2(lb + bh + lh)

= 2 (20 + 12 + 15)

= 2(47)

= 94 m^2
