Answer:
Here you go Hope it helps!!
Step-by-step explanation:
Answer 16 cubic cm (cm^3)
Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube
Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm
Area of circle is πr^2
Diameter is given =20 cm
Radius r=d/2=20/2=10cm
A=3.14×100
A=314 cm^2
