Please can you help me to convert 1.05m³ in m² @ a 10mm depth, and show me the workings out. Thanking you in advance.
Please try to word your questions more clearly.
A will assume you have sheet material $\displaystyle 10$ mm thick with a volume of $\displaystyle 1.05$ cubic metres.
$\displaystyle 10$ mm is $\displaystyle 0.01$ m, let the area be $\displaystyle A$, then:
$\displaystyle A \times 0.01=1.05$
$\displaystyle A=105 $ square metres.
