Question

calcule a area total e a medida diagonal de um cubo cujo volume é 125 m 3

Answer 1

dados :
>>>>>>>>
Volume = Vol. = 125m^3

Volumen do cubo :
=================
Vol. = a^3
125 = a^3
a^3 = 125
a = \3/125
a = 5m

Area total do cubo :
==================
At = 6 x a^2
At = 6 x (5)^2
At = 6 x 25
At = 125 m^2

Diagonal do cubo :
=================
D = a . \/3
D = 5.\/3 m
