oblicz objętość i pole powierzchni prostokąta o wymiarach 1cmx2cmx3cm
szybko plisss daję najjj
V = a*b*c
V = 1 * 2 * 3
V = 6cm^^
Pc = 2ab + 2ac + 2bc
Pc = 2(1*2) + 2(1*3)+ 2* (2*3)
PC = 4+6+12
PC = 22 cm^
^^ - sześcienne
^ kwadratowe
Raczej prostopadłościanu !
V = a*b*c = 1 cm* 2 cm * 3 cm = 6 cm^3
=================================
P = 2*( a*b + a*c + b*c) = 2*( 1*2 + 1*3 + 2*3 ) cm^2 = 2*11 cm^2 = 22 cm^2
