Alex is designing wooden boxes to store his books. Each box measures 15in by 12 in by 10 in. To know how much wood to buy, he needs to find the surface area of each box. What is the surface area of the box?

I believe the surface area is 900 in.

Step-by-step explanation: 15 x 12 = 180    15 x 10 = 150     10 x 12 = 120      120 + 180 + 150 = 450          450 x 2 = 900      

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
