Answers:
- Volume = 90 cubic inches
- Surface area = 126 square inches
- Material Cost = Not sure (see the explanation below)
=========================================
Step-by-step explanation:
L = 6 inches = length
W = 3 inches = width
H = 5 inches = height
----------------------
V = volume
V = L*W*H
V = 6*3*5
V = 90 cubic inches is the volume
----------------------
SA = Surface Area
SA = 2*(LW + LH + WH)
SA = 2*(6*3 + 6*5 + 3*5)
SA = 126 square inches is the surface area
-----------------------
Unfortunately there isn't enough information to know the material cost. Please post the full problem, and any other relevant information connected to this question.
