a = 2 cm
h = 8 cm
V = Pp *h
Pp = 6 * [ a^2 p(3)/4] = 1,5 a^2 p(3)
czyli
V = 1,5 a^2 p(3)* h = 1,5 *( 2 cm)^2 *p(3)* 8 cm = 1,5* 4 cm^2 * p(3)* 8 cm
V = 48 p(3) cm^3
=================
Masa gadżetu
m = V * 0,7 g/ cm^3
m = 48 p(3) cm^3 * 0,7 g/ cm^3 = 33,6 p(3) g
Odp, Gadżet ma masę 33,6 p(3) g. ( około 58,13 g ).
