Sasha's grandmother loves to travel. She sends Sasha postcards from all around the world. Sasha keeps the postcards in a special
box. The box has a square base and a square pyramid for a lid.What is the combined volume inside the box and lid?
1 answer:
To find the total volume of the box, you will find the volumes of each separate piece.
Use the formulas for finding the volumes of each:
V = 1/3 Bh (pyramid); B stands for the area of the base shape
1/3 x 8 x 8 x 3
V = 64 cubic inches
V = Bh (prism)
8 x 8 x 4
V = 256 cubic inches
256 + 64 = 320 cubic inches
The total volume of the box is 320 cubic inches.
