2 answers:
Answer:
56 yd²
Step-by-step explanation:
The surface area of the given triangular prism is made up of:
- 2 congruent triangles
- 2 congruent side rectangles
- 1 base rectangle
Area of the <u>triangle</u> = 1/2 × base × height
= 1/2 × 6 × 4
= 12 yd²
Area of the <u>side rectangle</u> = width × length
= 2 × 5
= 10 yd²
Area of the <u>base rectangle</u> = width × length
= 2 × 6
= 12 yd²
<u>Total Surface Area</u> = 2 triangles + 2 side rectangles + base rectangle
= 2(12) + 2(10) + 12
= 24 + 20 + 12
= 44 + 12
= 56 yd²
