Answer:
148 square inches
Step-by-step explanation:
Step 1: finding the area of the base (upper base plus lower base)
2( L x W).
2 (6in. x 5in.)
2( 30 square inches.)
60 square inches
Step 2: finding the area of first 2 sides
2 ( l x w)
2 ( 5in x 4in)
2 ( 20 square inches.)
40 square inches
step 3: finding the area of the last 2 sides
2(lxw)
2(4in.x 6in.)
2(24 square inches.)
48 square inches
step 4: combine all the answers.
60 square inches. + 40 square inches. + 48 square inches = 148 square inches
Keeping in mind that for a cost C(x) and profit P(x) and revenue R(x), the marginal cost, marginal profit and marginal revenue are respectively dC/dx, dP/dx and dR/dx, then
