Step-by-step explanation:
In the mensuration of a triangular prism we can find the total surface area by solving for the areas of individual shape.
The triangular prism consist of
1. three rectangular surfaces
2. two triangular surfaces.
Hence the total surface area is the sum of the areas of the rectangular surface
= 
and the sum of all areas of triangular surfaces
= 
<u><em>In summary just find the area of each shape and add them together.</em></u>
Answer:
3
Step-by-step explanation:
7 1/2 ÷ 2 1/2
=15/2 ÷ 5/2
=15/2 ×2/5
=3
Because the prices are different, you need to use two variables, one for each price.
Let the price for the plain one be X and the price for the printed one be Y.
You would multiply the number of each shirt by the variable:
3 plain would be 3X and 2 printed would be 2Y.
You then need to add those together to get the total cost:
Total cost = 3X + 2Y
