the width of a rectangle is w, w>or equal to 30cm and length is also >or equal to 30cm. Four squares of length 10cm are removed from the 4 corners of the rectangle. The sides are folded up. What is the volume of the resulting thing. I thought it is 10(w-20)^2 but can’t find that option. Is there anything wrong with my approach
For the 3D figure
- L - 20 will be the length of the base of the cuboid
- W - 20 will be the width of the base of the cuboid
- 10 will be the height of the cuboid
thanks
