Answer:
7
Step-by-step explanation:
Total concrete for slabs
24 * 24 * 1 = 576 ft³
Additional 20 %
By rule of three
if 576 ⇒ 100
x?? ⇒ 20 x = 115,2
And there are 2 slabs, the total volume of concrete is:
Q(t) = 2* (576 + 115,2 ) Q(t) = 1382,4 ft³ (1)
If the truck can carry a maximum of 8 yd³, as 1 ft³ = 0,037 yd³
then a truck can carry a maximum of
8/ 0,037 = 216,21 ft³
Now the total quantity is 1382,4
Then
1382,4/216,21 = 6,39
And as nobody can send a fraction of a truck , the fewest number of truck is 7
The orientation of the solid is odd, but here is what I see.
24+24+39+52+65= 204 units^2
