An oblique prism has trapezoidal bases and a vertical height of 10 units. which expression represents the volume of the prism? 10x3 cubic units 15x2 cubic units 20x3 cubic units 30x2 cubic units

image is missing in the question. refer to the attached image.

this question is based on concept of volume of solid figures.

volume of oblique prism is given by =base area height

since an oblique prism has trapezoidal bases.

so, area of trapezoid =

since height of trapezoid, h=x , a=x and b=2x

therefore,

area =

area =

given that the vertical height of the prism is 10 units.

so, the volume of prism = base area height

= cubic units.

therefore, option 2 is the correct answer.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
