Frank got a gift for his sister and put it in a shoebox.



Note: Figure is not drawn to scale.

Now, he wants to wrap it with wrapping paper. If the length of the shoebox measures 12 in, the width measures 6 in, and the height measures 5 in, how much wrapping paper does he need to cover the shoebox?
A.
648 sq in
B.
162 sq in
C.
486 sq in
D.
324 sq in

Respuesta :

  • L=12 in
  • B=6in
  • H=5in

We need TSA

  • 2(LB+BH+LH)
  • 2(12×6+5×6+12×5)
  • 2(72+30+60)
  • 2(162)
  • 324in²

Answer:

D. 324 in²

Step-by-step explanation:

Given :

Length of shoebox = 12 in

width = 6 in

height = 5 in

The Total surface area of cuboid = 2(lw + lh + wh )

=> 2 (12×5 + 12×6 + 5×6 )

=> 2( 60 + 72 + 30 )

=> 2( 162)

=> 324 in²
