Question

uma prisma quadrangular tem aresta de base igual a 3 cm e aresta lateral iagual a 7 cm calcule a area da base, a area lateral , area total e o volume desse prisma

Answer 1

area da base : 

$A b = a ^{2} \\ Ab = 3 ^{2} \\ Ab = 9$


area total : 

$At = Al + 2Ab \\ At = 7 + 2.9 \\ At = 7 + 18 \\ At = 25$


volume : 

$V = a ^{2} .b \\ V = 3 ^{2} .7 \\ V = 9 . 7 \\ V = 63$
