Explicación paso a paso:
[tex]atotal = abase + a \:caras \: \\ hipotensa = {h}^{2} = {10}^{2} + {6}^{2} = \sqrt{136} = 11.7cm[/tex]
[tex]a = (6 \times 3) + (3 \times 11.7) + (10 \times 3) + 2 \times \frac{10 \times 6}{2} \\ a = 18 + 35.1 + 30 + 60 \\ a = 133.1 {cm}^{2} [/tex]
[tex]v = \frac{abase \times h}{2} \\ v = \frac{18 \times 10}{2} \\ v = 90 {cm}^{3} [/tex]
