Question

Given $f={cd}^3$, $f=450$, and $d=10$, what is $c$?

• A. $0.45$
• B. $4.5$
• C. $15$
• D. $45$
• E. $150$

Answer 1

The correct option is A $0.45$

Given, $f=c{d}^3$, substitute $f=450$ and $d=10$ in $f=c{d}^3$, we get

$450=c(10{)}^3$

$\Rightarrow 450=1000c$

$\Rightarrow c=\frac{450}{1000}$

$\Rightarrow c=0.45$

Hence, option A is correct.
