Answer 1

how many cubic meter of each can be excavated from a rectangular well 28m deep and base dimension are 10 m and 7m

Solution:

Our rectangular well is a kind of rectangular prism.

In our case we have:

l=10m

w=7m

h=28m

Consider the formula and make a conclusion:

$$V = 10 \cdot 7 \cdot 28 = 1960(m^3)$$

and that's our answer.

Answer: 1960(m³).
