{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  {9}^{2}  +  {9}^{2}  =  {c}^{2}  \\  {81} + 81 =  {c}^{2}  \\ 162 =  {c}^{2}  \\  \sqrt{162}  =  \sqrt{ {c}^{2} }  \\ 12.73 = c
the length of the diagonal is 12.73

Vanyuwa [196]

Answer:

400cm²

Step-by-step explanation:

Total surface area of a prism includes the area of the top and bottom triangle sides of the prism, plus the area of all 3 rectangular sides.

Base & Bottom triangle area: 2 x [(8 x 15)/2] = 120cm²

Side triangle area: 17 x 7 + 8 x 7 + 15 x 7 = 280cm²

Total surface area = 280 + 120 = 400cm²
