Question

halla la área lateral y total del prisma triangular ​

Answer 1

Explicación paso a paso:

área lateral

$a = b \times h \\ a = (15 \: cm)(5 \: cm) = 75 \: {cm}^{2} \times 2 = 150 \: {cm}^{2} \\ a = (15 \: cm)(4 \: cm) = 60 \: {cm}^{2}$

$a = \frac{b \times h}{2} \\ a = \frac{(4 \: cm \times 3 \: cm)}{2} = \frac{12 \: {cm}^{2} }{2} = 6 \: {cm}^{2} \times 2 = 12 \: {cm}^{2}$

área total

$a = (\frac{b \times h}{2} )h \\ a = (\frac{(4 \: cm)(3 \: cm)}{2} )15 \: cm \\ a = ( \frac{12 \: {cm}^{2} }{2} )15 \: cm \\ a = (6 \: {cm}^{2} )(15 \: {cm} ) \\ a = 90 \: {cm}^{3}$
