Answer :
Top and Bottom = 2 (14 x 8)
TB = 2 (112)
TB = 224
Sides 1 and 3 = 2 (8 x 12)
S13 = 2 (96)
S13 = 192
Sides 2 and 4 = 2 (14 x 12)
S24 = 2 (168)
S24 = 336
224 + 192 + 336 = X
X = 752
Answer:
Surface area of the box is 752 inches²
Step-by-step explanation:
Chuck is covering a box that he made for his car speakers in carpet.
Dimensions of the box are Length = 14 inches, Width = 8 inches and Height = 12 inches.
Now we have to calculate the surface area of the box to be covered.
Since formula for surface area of a box is given by
S = 2(lw + hl + hw)
where l = length
w = width
h = height
Now we put the values in the formula
S = 2(14×8 + 14×12 + 8×12)
= 2(112 + 168 + 96)
= 2(376)
= 752 inches²
Therefore, surface area of the box is 752 inches²
