Odpowiedź:
a)
P = 6*a^2 = 6*( 8 cm)^2 = 6*64 cm^2 = 384 cm^2
V = a^3 = ( 8 cm )^3 = 512 cm^3
=============================================
b) P = 2*(a*b + a*c + b*c) = 2*( 7*14 + 7*9 + 14*9) = 2*( 98 + 63 + 126) =
= 2*287 = 574
P = 574 m^2
============
V = a*b*c = 7*14*9 = 882
V = 882 m^3
============
