What will be the cost of painting the walls of a room 5.6 m long, 4.3 m wide and 4 m high at Rs 65 per sq. metre?
Answers
Answer:
The cost of painting is ₹6713.2.
Step-by-step explanation:
First we need to find the L.S.A and the area of top side of the room.
L.S.A of the room = 2h(l+b)
=2x4 (5.6+4.3)
= 8 x 9.9
= 79.2m^{2}m
2
Area of the top side = L x B
= 5.6 x 4.3
= 24.08m^{2}m
2
Area to be painted = L.S.A + Area of the top side
= 79.2 + 24.08
= 103.28m^{2}m
2
Cost of Painting = ₹65 x Area of to painted
= ₹65 x 103.28m^{2}m
2
= ₹6713.2.
∴The cost of painting is ₹6713.2
Answer:
L = 5.6 m
b = 4.3 m
h = 4 m
cost = ₹ 65/m
LSA = 2(l+b)h
= 2(5.6 + 4.3 ) 4
= 8*9.9
= 79.2 m
adding top area =
79.2+24.08
103.08 m
cost = LSA * rate
= 103.08 * 65
= ₹ .6,700.2
