Answer:
2769.592cm³
Explanation:
Calculate the volume of the cuboid below and add to the volume of the rectangular pyramid above
Volume of cuboid = Lenght x width x height
V = 26.6 x 11.4 x 7.2
V =2183.328cm³
Volume of rectangular pyramid 1/3lwh or 1/3Bh
V = 1/3 x 26.6 x 11.4 x 5.8
V = 1758.792/3
V = 586.264
Add both volumes 2183.328 + 586.264
