Answer:
252 cm
Explanation:
The volume of the figure can be found in two ways, one finding the volume of a larger rectangular prism and subtracting the missing pieces:
6×5×10=300
The area of one missing piece is 1×4×6=24, and the other is the same, so 300-48=252 gives the volume of that solid.
Otherwise, you can split the solid into three rectangular prisms, recognizing that the top and the bottom ones are congruent. Then you would have (6×5×3)×2=180 for the top and bottom rectangular prisms and (6×3×4)=72 for the middle one, giving you a volume of 180+72=252.
