Answer:7

Step-by-step explanation:Total concrete for slabs24 * 24 * 1 = 576 ft³Additional 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
