Question

Calculate the surface area and volume of your room. Write all dimensions neatly. Take approx multiples of 10 for easy calculations.

Answer 1

Dimensions

Length = 5m

Breadth = 4m

Height = 3m

Thus,

Surface are of room is

$2(lb + bh + lh)$

So,

2( 5×4 + 4×3 + 5×3 ) = 2( 20 + 12 + 15) m^2

= 2( 47 ) m^2 = 94 m^2

Now, Volume = lbh = 5 × 4 × 3 m^3 = 60 m^3
