Pole podstawy - prostokąt
[tex]p = 20mm \times 50mm = 1000 {mm}^{2} [/tex]
V=900mm^3
wzór na objętość ostrosłupa
[tex]v = \frac{1}{3} \times p \times h[/tex]
[tex]900 {mm}^{3} = \frac{1}{3} \times 1000 {mm}^{2} \times h \: \: \: \: | \times 3 \\ 2700 {mm}^{3} = 1000 {mm}^{2} \times h \: \: \: \: | \div 1000 \\h = 2.7 \: mm[/tex]
V = 1/3 x Pp x h
h = V / (Pp x 1/3)
h = 3 * V / Pp
Pp = 20mm x 50mm = 100 mm2
h = 3 x 900 / 100 = 3 x 9 = 27 mm
h = V / (Pp x 1/3)
h = 3 * V / Pp
Pp = 20mm x 50mm = 100 mm2
h = 3 x 900 / 100 = 3 x 9 = 27 mm
