Question

Sally has made a jewelry box that is 8 inches long. 3 inches deep and 5 inches tall. She has painted all but the bottom of the box. What is the area of the painted portion of the jewelry box?

Answer 1

Answer:

224 inches painted

Step-by-step explanation:

for the inside of the box,

8 * 5 = 40 + 40 = 80 (represents the 2 long side multiplied by the tall)

3 * 5 = 15 + 15 = 30 (represents the 2 deep sides multiplied by the tall)

8 * 3 = 24 (represents the inside bottom of box)

80 + 30 + 24 = 134 (inside)

for the outside,

8 * 5 = 40 + 40 = 80 (represents the 2 long side multiplied by the tall)

3 * 5 = 15 + 15 = 30 (represents the 2 deep sides multiplied by the tall)

80 + 30 =110 (outside)

total,

224 inches painted

i hope this helps!
