The statements that are true about the volume of the greenhouses are: B and E.
Volume of rectangular prism = (length)(width)(height)
Volume of rectangular pyramid = 1/3(length)(width)(height)
Volume of Greenhouse 1 = volume of rectangular prism + volume of rectangular pyramid = (12)(12)(10) + 1/3(12)(12)(8) = 1,824 m³
Volume of Greenhouse 2 = volume of rectangular prism + volume of triangular prism = (12)(12)(10) + 1/2(12)(8)(12) = 2,016 m³
Difference between the spaces in both greenhouses = 2,016 - 1,824 = 192 m³
Therefore, the true statements about the greenhouses are: Option B and Option E.
