Answer:
7c^2
Step-by-step explanation:
I'm assuming you meant "9c^2 - 4c^2 + 2c^2." This comes to:
(9 - 4 + 2)*c^2, or 7c^2.

Answer:
yes i noticed that
Step-by-step explanation:
IF the estimates are 100% accurate, then the maximum volume of concrete is the product of the maximum dimensions, namely
Vmax=18.32*12.22*0.55=123.13 m^3
and the minimum volume of concrete is the product of the minimum dimensions
Vmin=18.28*12.18*0.45=100.19 m^3
the uncertainty is therefore 123.13-100.19=22.94 m^3
On the practical side, to this uncertainty must be added to
- squareness of the formwork
- evenness of the surface of the crushed stones on which the foundation sits on
- excess of concrete delivered by the truck
- volume of air bubbles trapped in the the concrete, ...
