Question

A toy shown in the figure is made of two solids -a
cuboid and a cone. The dimensions of the cuboid
are 5 cm x 4 cm x 3 cm and radius and height of
the cone are 2 cm and 3 cm respectively. The total
surface area of the toy (taking n = 3.14 and 13
3.6) is

Answer 2

Total surface area of the toy is 125$cm^{2}$

Explanation:

For cuboid

l = 5cm

w = 4cm

h = 3cm

For cone

r= 2cm

h= 3cm

π = 3.14

TSA of cuboid = 2(lh + lw +hw)

TSA of cone = πrl + π$r^{2}$

Therefore putting values

2(5x4 + 5x3 + 3x4) + 3.14 x 2 x 3 + 3.14 x 4

The final value is

= 125.4 $cm^{2}$
