Question

I can’t fail this and i have no idea how to do these please help!

Answer 1

Answer: 675 ft cubed

Explanation:

You can solve this by dividing the figure into two shapes, similar to the diagram. Let's start with the green shape, the cube.

To solve a cube, multiply b*w*h. Here, it is 15*15*15, which is 3375 ft cubed.

Now, let's move on to the pyramid. The formula is 1/3Bh. Our base is 15*15, since that's the length times width. Therefore, our base is 225 ft squared. Now, we multiply it by the height, 9. This is 2025 ft cubed. Finally, we take 1/3 of it, so we divide it by 3. Our answer is 675 ft cubed.

hope this helps!

Answer 2

Answer: To find the answer, add the volume of the cube and the pyramid. To find the volume of the pyramid, it says it in the bottom right corner. V = 1/3 x base x height. The height is 9 feet, and the base is 15 x 15 feet.

To find the volume of the cube, multiply length x width x height, which is all 15.
