Question

a right rectangular prism and an oblique triangle are both 12 cm tall and have the same volume. which statement must be true about the two solids

Answer 1

I'm assuming you mean "oblique triangular prism"

using this formula `volume of prism = (area of base)*(height of prism)`

we know for a fact that if the volume and heights are the same for both figures, then the areas of the bases must also be the same (to ensure the equation holds true)
