Question

dm by 5 dm. Find the number of stones required.


Please help me out!!!!!!

Answer 1

200 stones.

Explanation:

Given that the verandah is 40 meters long by 15 meters wide, and that it is going to be paved with stones that measure 6 decimeters by 5 decimeters, to determine the amount of stones that should be used, the following calculation must be performed:

1 m = 10 dm

Verandah's surface: 40 x 15 = 600m2

Stones' surface: 6 x 5 = 30dm2 = 3m2

600/3 = X

200 = X

Therefore, 200 stones should be used to pave the entire verandah.
