Its 10 i just times by 2 then i got a answer then i looked and said 5 each side seems right
(2*40%+x*10<span>0%)/(2+x) = 70%; calculate x !</span>
To make a LINE that is 12 cm long, you'd need (12 / .75) cubes or sixteen cubes.
To make a CUBE you'd need 16^3 cubes or 16*16*16 cubes or 4,096 three quarter centimeter cubes.
