Answer 1

Explicación paso a paso:

Area Lateral

$A_L = 2( \frac{(5)(18)}{2} ) + 2( \frac{(8)(18)}{2} ) \\ A_L = 2(45) + 2(72) \\ A_L = 90 + 144 \\ \boxed{A_L = 234 \: {cm}^{2} }$

Area de la base

$A_B = (8)(5) \\ A_B = 40 \: {cm}^{2}$

Area Total

$A_T = A_B + A_L \\ A_T = 40 \: {cm}^{2} + 234 \: {cm}^{2} \\ \boxed{A_T = 274 \: {cm}^{2} }$
