I think its 8 because 64 divided by 8 is 8.
It’s 3 loads and $195 because you multiply 52 by 2 to get the total amount of bricks and then you divide 104 by 45 and you have a remainder of 14 which would be the last load and then divide 65 or whatever the price of the load of bricks to get 195
To find surface area, we can use the equation:
SA=2lw+2wh+2lh, where:
l=10 in
w=3 in
h=7 in
SA=(2)(10)(3)+(2)(3)(7)+(2)(10)(7)
SA=60+42+140
SA=242 in²
