Surface area = 2(lw) + 2(wh) + 2(lh)
2(4 * 5) + 2(5 * 15) + 2(4 * 15)
2(20) + 2(75) + 2(60)
40 + 150 + 120
310 square inches
Find the difference between the two times
= 4 2/5 - 2 1/4
convert each mixed number to an improper fraction
= 22/5 - 9/4
change to common denominator (20)
= 88/20 - 45/20
subtract numerators only
= 43/20
change back to mixed number
= 2 3/20
