Question

A cube has length 0.6 m. To paint it
from outside, what will be cost if the rate
of paint is Rs. 50 per square metre?​

Answer 1

Answer:

The cost of painting the cube is 108 Rs.

Step-by-step explanation:

To find out the cost of painting the cube from the outside, we multiply the cost by the surface area.

0.6 m = 60 cm

Surface area = 6a²

Surface area = 6*60² cm

Surface area = 6*3600 cm²

Surface area = 21600 cm² = 2.16 m²

Cost of painting - Rs. 50/m²

2.16 m²*50 = 108

Therefore, the cost of painting the cube is 108 Rs.

Hope this helps you.

Answer 2

Given:

• Length of the cube = 0.6m

To find:

• Cost of painting it, if the rate of paint is Rs. 50 per square meter.

Solution:

• Total surface area of cube = 6a²

⇒ 6 × (0.6)²

⇒ 2.16m²

• Cost for painting it at the rate of Rs. 50 per square meter,

⇒ Rs. (50 × 2.16)

⇒ Rs. 108

Hence, the cost of painting it is Rs. 108.
