Question

Lauren bought a rectangular box

that is 6 inches long, 10 inches wide,
and 4 inches high. She wants to
cover it in fabric. The fabric costs
$0.25 per square inch. How much
will the fabric cost?

Answer 1

Explanation:

SA = 2(l x w) x 2(l x h) x 2(w x h)

= (2x6x10) x (2x6x4) x (2x10x4)

= 120 x 48 x 80

= 460800 inches

460800 x $0.25

= $115200
