the minimum number of cubes.

Top Front Right Side

1 The numbers of cubes counted from the front and side 2
views at the bottom and on the right of the top view are 2
shown on the right. Write how many cubes are stacked 3
under each uncolored space. 333

2 The colored spaces represent spaces that can change the 2
total number of cubes used to make the solid figure. 2
Write the number of cubes in each space and find the 3
total number of cubes used to make the solid figure. 333
