Answer:
(1) 292 sq ft
(2) 346 sq in
Step-by-step explanation:
Surface Area
(1)
Triangular Prism
Given that:
- Base (b) = 7 ft
- Height (h) = 6 ft
- Hypotenuse (y) = 9 ft
- Depth (d) = 10 ft
Find the surface area!
Surface area =
bh + d(b+2y) =
(7 × 6) + (10×(7+(2×9))) =
42 + 250 =
292 sq ft ✅

(2)
Cuboid
Given that:
- Length (L) = 11"
- Width (W) = 10"
- Height (H) = 3"
Find the surface area!
Surface area =
2LW + 2LH + 2WH =
(2×(11×10)) + (2×(11×3)) + (2×(10×3)) =
220 + 66 + 60 =
346 sq in ✅
