Jordan purchased a piece of fabric that is 18 cm x 18 cm in order to make a tent for her little sister‘s dolls using the dimensions for the tent shaped as a triangular prism. How much fabric will be left over will it be 184 cm 324 cm 240 cm or 84 cm and the number on me triangular can’t is on the front bottom is 4 cm on the right side. The length is 12 cm on the left side. The length is 7 cm that is your calculation.
To calculate the amount of fabric needed for the triangular prism tent, we need to find the total surface area of the tent.
The front side of the tent is a triangle with base 4 cm and height 7 cm.
Area of the front side = 1/2 * base * height
Area of the front side = 1/2 * 4 cm * 7 cm = 14 cm²
There are two triangular sides to the tent. Each triangular side has a base of 4 cm and height of 12 cm.
Area of one triangular side = 1/2 * base * height
Area of one triangular side = 1/2 * 4 cm * 12 cm = 24 cm²
Total area of both triangular sides = 2 * 24 cm² = 48 cm²
Total surface area of the tent = Front side area + 2 * Triangular side area
Total surface area = 14 cm² + 48 cm² = 62 cm²
Given that the fabric purchased is 18 cm x 18 cm, the area of the fabric is 18 cm * 18 cm = 324 cm²
Therefore, the amount of fabric left over after making the tent is:
324 cm² (fabric purchased) - 62 cm² (fabric used for tent) = 262 cm²
So, the correct answer is 262 cm.
