The cross section of rectangular prism a measures 3 units by 2 units. the cross section of triangular prism b has a base that measures 4 units and a height of 3 units. if the length of each prism is 3.61 units, which statement is true?
volume a = 1/2 (volume b)
volume a = 2 (volume b)
volume a = 1/3 (volume b)
volume a = volume b
i think its the first one but i want to make sure, : ) ty
