About how many cubes were used to make this figure? A. about 40 B. about 70 C. about 100 D. about 140
natta225 [31]

Answer:

Around 100,i.e. 105

Step-by-step explanation:

In the given cube

Length of the cube = 7 unit cells

Breadth of the cube = 3 unit cells

Height of the cube = 5 unit cells

Therefore the number of unit cubes required to make such big cube is nothing but the volume of the big cube = length*breadth*height

⇒Number of cubes used to make that big cube= 7*5*3

                                                                               = 105

Hence, option D (around 100) is the correct answer
