Answers
Answer:
24000
Step-by-step explanation:
6l²=6×10²=600
600×40=24000
The cost of tin required to make the cube at the rate of Rs. 40 per m² is Rs. 2.4.
Step-by-step explanation:
The edge of the cube, a = 10 cm = 0.1 m
We know that to find the tin required to make the cube with an edge of 10 cm or 0.1 m we have to find the total surface area of a cube i.e.,
T.S.A of a cube = 6 a² = 6 * (0.1)² = 6 * 0.01 = 0.06 m²
The cost of tin is given as Rs. 40 per meter square
Thus,
The total cost of the tin required to make a cube will be,
= 0.06 m² * 40
= Rs. 2.4
