Answer:
a)90 square inches
b)104 cubic inches
Step-by-step explanation:
Dimensions of the bigger box
W= 8 in
H=11 in
D= 3 in
Dimensions of the smaller box
w= 6 in
h= 10 in
h= 2.5 in
therefore, difference in the area of the cupboard
=2[ WH+HD+WD] - 2[wh+hd+wd]
= 2[8*11+11*3+8*3]- 2[6*10+10*2.5+6*2.5]
=290- 200= 90 square inches
volume of the large cupboard = WHD= 8*11*3= 264 cubic in
volume of the small cupboard= whd= 6*10*2.5= 150 cubic in
therefore, 264-150= 114 cubic in more cereal does the large box hold than the small box
