The cost for the contractor to have all the dirt hauled away for a foundation of 12 feet long, 9 feet wide and 6 feet deep is $720
<h3>Volume of rectangular prism</h3>
volume of a rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 12 ft
w = 9 ft
h = 6 ft
volume of the foundation = 12 × 9 × 6
volume of the foundation = 648 ft³
Therefore, the contractor pays $180 per load for the trucks remove the dirt.
648 cubic feet = 24 cubic yard
6 cubic yards = 1 truck load
24 cubic yard =
cross multiply
number of truck load = 24 / 6 = 4 truck loads
Hence,
1 truck load = $180
4 truck load =?
cross multiply
cost = 4 × 180 = $720

Answer:
11
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
g(x) = x² +2
g(3) = 3² +2 = 9+2
g(3) = 11
