3cm
V = 3cm * 3cm * 3cm = 27cm^3
ppc = 3 cm * 3cm * 6 = 54cm^2
10cm
V = 10cm * 10cm * 10cm = 1000 cm^3 = 1 dm^3
ppc = 10cm * 10cm * 6 = 600cm^2
8dm
V = 8dm * 8dm * 8dm = 512dm^3
ppc = 8dm * 8dm * 6 = 384dm^2
1,8cm
V = 1,8cm * 1,8cm * 1,8cm = 5,832cm^3
ppc = 1,8cm * 1,8cm * 16 = 19,44cm^2
0.16dm = 1,6cm
V = 1,6cm * 1,6cm * 1,6cm = 4,096cm^3
ppc = 1,6cm * 1,6cm * 6 = 15,36cm^2
Zadanie
a)
a = 3 cm
P = 6 · a²
P = 6 · 3² = 6 · 9 = 54 cm²
V = a³
V = 3³ = 27 cm³
b)
a = 10 cm
P = 6 · a²
P = 6 · 10² = 6 · 100 = 600 cm² = 1 dm²
V = a³
V = 10³ = 1000 cm³ = 1 dm³
c)
a = 8 dm
P = 6 · a²
P = 6 · 8² = 6 · 64 = 384 dm²
V = a³
V = 8³ = 512 dm³
d)
a = 1,8 cm
P = 6 · a²
P = 6 · 1,8² = 6 · 3,24 = 19,44 cm²
V = a³
V = 1,8³ = 5,832 cm³
e)
a = 0,16 dm = 1,6 cm
P = 6 · a²
P = 6 · 1,6² = 6 · 2,56 = 15,36 cm²
V = a³
V = 1,6³ = 4,096 cm³
