Answer:
1. 172 m ²
2. 226.56 m ²
3. 336 cm ²
4. 296 inch ²
5. 461 cm ² wrapping paper
Explanation:
1. 32+112+28 = 172 m ²
2. 120+ 72 + 34.56 = 226.56 m ²
(half base 3.6 x 4.8 = 17.28 x 2 = 34.56)
3. Triangle face 48/2 = 24cm x 2 = 48 = 48 +72+96+120 = 336 cm ²
4. 9x3 = 27 3x 10 = 30 9x 10 = 90 90+30+27 = 147 147 x 2 = 296 inch ²
5. Right Angle face Triangular prism
1/2 10.5 x 10 = 1/2 105 = 52,5
x2 = 105cm ²
10.5 x 8 = 120c
x2 = 240 cm ²
8x14.5 = 116cm
105+240+116 = 461 cm²
