Q. Use the net below to calculate the surface area of this triangular prism.End(5)O.i2Show grid0
Identify Shapes: Identify the shapes that make up the surface area of the prism: two triangular ends and three rectangular sides.
Calculate Triangle Area: Calculate the area of one triangular end. Area of a triangle = 21×base×height. Assuming the base and height of the triangle are both 5 units, Area = 21×5×5.
Calculate Total Triangle Area: Perform the calculation for the triangular area: 21×5×5=12.5 square units.
Calculate Rectangular Sides Area: Since there are two triangular ends, multiply the area of one triangle by 2: 2×12.5=25 square units.
Add Rectangular Sides Areas: Calculate the area of the three rectangular sides. Assuming the length of the prism is l, the areas are: 5×l, 5×l, and 5×l for each of the three sides.
Calculate Total Surface Area: Add the areas of the rectangular sides: 5×l+5×l+5×l=15×l square units.
Calculate Total Surface Area: Add the areas of the rectangular sides: 5×l+5×l+5×l=15×l square units. Add the areas of the triangular ends and the rectangular sides to get the total surface area: 25+15×l square units.
