Question

A square plat of side $xcm$ is $8mm$ thick .if it's volume is $2880c{m}^3,$,find the value of $X.$

Answer 1

Step: Find the value of $X.$

Volume of the plate$=$ Area of the square plate$\times$ thickness $=2880c{m}^3$

Side$=xcm$

We need to find $x$
$x^2\times 8mm=2880c{m}^3$
$$\begin{gathered} \Rightarrow x^2\times 0.8cm=2880c{m}^3 \\ \Rightarrow x^2=\frac{2880}{0.8} \\ \Rightarrow x^2=\frac{28800}{8} \\ \Rightarrow x=60cm \end{gathered}$$

Hence, the value of $x=60cm$.
