Answer:
Your answer is N = 1000
Step-by-step explanation:
Given :
To find :
solution:
area of the square = A²
A² = 49
A = √49
A = 7 cm
side of the big cube = 7 cm
volume of the big cube = A³
= 7³ = 343 cm³
volume of small cube = a³
= 0.7³
= 0.343 cm³
number of small cubes fit into large cube = (N x 0.343 = 343)
N = 343/0.343
N = 1000
We need 1000 small cubes to fill the large cube fully.
