Answer:
9. 108 cm^2
10. 1,080 m^2
Step-by-step explanation:
9. 2(3x4) = 24/2 = 12 (for right triangles)
8x5 = 40 (base rectangle)
3x8 = 24 (left slanted side of prism)
4x8 = 32 (right slanted side of prism)
12 + 40 + 24 + 32 = 108
10. 2(8 x 15) = 240/2 = 120 (for right triangles)
24 x 15 = 360 (base rectangle)
24 x 17 = 408 (right slanted side of prism)
8 x 24 = 192 (left slanted side of prism)
120 + 360 + 408 + 192 = 1,080
