These are both conversion problems.
3. Convert square meters to square feet.
Thanks to conversions, 98 square meters = 1,054.86 square feet.
4. A conversion from cubic meters to cubic feet.
You will need 38 cubic meters, which is 1,341.96 cubic feet. It costs $12.00 per cubic foot, so it will cost $16,103.52 as that is 1,341.96 * 12.
Hope this helps!
