A jewelry box is in the shape of a right rectangular prism with a length of 8.25 cm, a width of 5.5 cm, and a height of 4.5 cm.

How many cm² of gift wrap is needed to completely cover the box?

Respuesta :

8.25*5.5*4.5=204.2 square centimeters
204.2 is your answer

214.5 is the correct answer 
SA = 2( lw + lh + wh )
2( 8.25 * 5.5 + 8.25 * 4.5 + 5.5 * 4.5)
2( 45.375 + 37.125 + 24.75) =107 .25
2 * 107.25 = 214.5
Surface are is 214.5 
So 214.5 cm of gift wrap is needed. Hope this helps Have a Great day :)
