Answer:
300cm
Step-by-step explanation:
the figure on the bottom would be “length x width x height” so it would be 4x6x12 and that would be
288cm
For the small figure on the top the length would be 1 because 4 - 3 is 1 ,
the width would be 12 and the height would be 1 because the 7 on the side is the height of the whole thing and the 6 is the height not including the figure on top. So for the top figure it would be 1x12x1 which would be
12cm
288+12 = 300cm
