Question

16 find the surface area of the right triangular prism. 9 in 12 in 15 in 10 in square inches

Explanation:

Step1: Calculate area of 2 triangular bases

Area of one right triangle: $\frac{1}{2} \times 9 \times 12 = 54$
Total for two triangles: $2 \times 54 = 108$

Step2: Calculate area of 3 rectangular faces

Area of first rectangle: $9 \times 15 = 135$
Area of second rectangle: $12 \times 15 = 180$
Area of third rectangle: $10 \times 15 = 150$
Total for rectangles: $135 + 180 + 150 = 465$

Step3: Sum all areas for total surface area

Total surface area: $108 + 360 = 468$

Answer:

468 square inches
