15 * 28 = 420. Should be your answer.
Answer:
416 in²
Step-by-step explanation:
Given that:
Height. h = 4 in
Length = 12 in
Width = 10 in
The surface area of a rectangular prism is obtained using the relation :
Surface Area, S = 2(lw + lh + wh)
S = 2[(10*12) + (10*4) + (12*4))
S = 2(120 + 40 + 48)
S = 2(208)
S = 416 in²
We can set up an equation with x as the price of one cup:
4x=0.96
x=0.96/4=0.24
Each cup is $0.24
