Answer:
D. 363 Let me know if you have any questions.
Explanation:
treat it as two figures. both look to be all made of rectangles, or in other words it is a rectangular prism. To find the volume of a rectangular prism just multiply the height, length and width together.
So let's label them small shape and big shape.
Big shape looks to have side lengths of 3 in, 12 in and 8 in, so multiply these together to get the volume. so 3*12*8 = 288 square inches.
Small shape will multiply 3*5*5 = 75. So the main shape is just the two pushed together, so you add the two. 288+75=363
