jordan purchased a piece of fabric that is 18 cm by 18 cm in order to make a tent for her little sister's dolls using the dimensions for the tent shaped as a rectangular prism how much fabric triangular prism how much fabric will be left over

To make a rectangular prism tent for her little sister's dolls, Jordan will need to cut out 6 pieces of fabric: 2 pieces for the top and bottom (18 cm by 18 cm), and 4 pieces for the sides (18 cm by the height of the tent).

Since the height of the tent is not given, let's assume it to be 36 cm for this calculation. So, each side piece will be 18 cm by 36 cm.

The total fabric needed for the rectangular prism tent will be:

2(top and bottom pieces) + 4(side pieces) = 2(18 cm * 18 cm) + 4(18 cm * 36 cm)
= 2(324 cm^2) + 4(648 cm^2)
= 648 cm^2 + 2592 cm^2
= 3240 cm^2

Now, since the total fabric purchased by Jordan is 18 cm by 18 cm, the total area of fabric bought is:

18 cm * 18 cm = 324 cm^2

The amount of fabric left over after making the rectangular prism tent will be:

324 cm^2 (total fabric purchased) - 3240 cm^2 (total fabric needed) = -2916 cm^2

Since the fabric needed is more than the fabric purchased, Jordan would need to buy more fabric to complete the tent.
