Answer:
3 ft²
Explanation:
==>Given:
Box J with the following dimensions:
L = 4.5ft
W = 3ft
H = 2ft
Box F:
L = 3ft
W = 3ft
H = 3ft
==>Required:
Difference between the surface area of box J and box F
==>Solution:
Surface area = 2(WL + HL + HW)
=>S.A of box J = 2(3*4.5 + 2*4.5 + 2*3)
= 2(13.5 + 9 + 6)
= 2(28.5)
S.A of box J = 57 ft²
=>S.A of box F = 2(3*3 + 3*3 + 3*3)
= 2(9 + 9 + 9)
= 2(27)
S.A of box F = 54 ft²
Difference between box J and box F = 57 - 54 = 3 ft²
