Chuck is covering a box that he made for his car speakers in carpet. if the box is 14 inches long, 8 inches wide, and 12 inches tall, what is the surface area of the box to be covered?

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

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
