Question

Calcular el área lateral y total de un cubo 8 cm de arista

Answer 1

Tenemos.

Arista (a) = 8cm

Area lateral = 4 * a²
Area lateral =  4 * 8cm * 8cm
Area Lateral = 256cm²

Area total = 6 * a²
Area total = 6 * 8cm * 8cm
Area total = 384cm²

Answer 2

Hola!

$al = 4xa ^{2} = 4x(8m) ^{2} = 4x64cm ^{2} = 256cm ^{2} \\ at = 6xa ^{2} = 6x(8cm ) ^{2} = 6x64cm ^{2} = 384cm ^{2}$
