The cube has area of base 256 mm2.

Calculate the edge length, volume and area of its surface.

Result

a =  16 mm
V =  4096 mm3
S2 =  1536 mm2

Solution:

S=256 mm2 S=a2=a a a=S=256=16 mmS=256 \ \text{mm}^2 \ \\ S=a^2=a \cdot \ a \ \\ a=\sqrt{ S }=\sqrt{ 256 }=16 \ \text{mm}
V=S a=256 16=4096 mm3V=S \cdot \ a=256 \cdot \ 16=4096 \ \text{mm}^3
S2=6 S=6 256=1536 mm2S_{2}=6 \cdot \ S=6 \cdot \ 256=1536 \ \text{mm}^2



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
