Complete Question
Adam wraps the top edge of the gift box shown with gold ribbon. The top and bottom edges of the box are square. If Adam has 24 1/4 inches of gold ribbon, does he have enough to decorate the top of the box?
Yes, he has enough ribbon to decorate the top of the box.
Step-by-step explanation:
From the above question, we are told that the volume of the box = 296cm³
Volume of the box = a³
296cm³ = a³
a = √296cm³
a = 6.6644437033cm
The side length of the box = 6.6644437033cm
The length of the ribbon = 24 1/4 inches
= 24.25 inches long.
Converting this to centimeters =
1 inch = 2.54cm
24.25 inches =
24.25 × 2.54 cm
= 61.595cm.
Length of the ribbon = 61.595cm.
Since from the above, we know the edges of the cube = square
Edge length of the box = 6.6644437033cm
The perimeter of a top of the box
= 4a
= 6.6644437033cm × 4
= 26.657774813 cm
Subtracting the perimeter of the top of the box from the length of the ribbon
61.595cm - 26.657774813 cm
= 34.937225187 cm ( ribbon left)
Therefore, he has enough ribbons left
