Answer 1

Answer:

135

Step-by-step explanation:

3×2×1.5=9m^3

cost= 9×15

135

Answer 2

The cost of digging the pit at the rate of Rs. 15 per cubic metre is Rs. 135.

•  Given dimensions of the pit are :

3 m, 2 m, 1.5 m

=> Volume of the pit = 3m × 2 m × 1.5 m = 9 m³

• Given,

Cost of digging per cubic metre of the pit = Rs. 15

Therefore, cost of digging the entire pit = Volume of the pit × Cost of digging per cubic metre

=> Total cost of digging = 9 m³ × Rs. 15 / m³ = Rs. 135

•  The cost of digging the pit is Rs. 135.
