The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = where a and b are the opposite parallel sides and h be the height of a trapezium.

In the first picture , we're provided - Length ( l ) = cm , breadth ( b ) = cm and height ( h ) = cm. Now, plug these known values and them find out the volume of given rectangular prism.

To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term if possible.

Hence , the volume is cubic centimetres.

In the second attachment , we're provided - 6ft and 7 ft are the opposite parallel sides and 3 ft is the height of the given trapezium.

Hence , The area of trapezium is

And we're done ! ♪
