Answer:
1111 cm³ (to nearest cubic cm)
Step-by-step explanation:
Given that,
radius of spherical magnets a scientist made = 1.02 cm
number of boxes = 250
Use 3.14 for π
Formula for volume of spherical magnets
4/3 x π x r³
4/3 x 3.14 x r³
4/3 x 3.14 x (1.02)³
4/3 x 3.14 x (1.061208)³
= 4.443 cm³
The volume of 250 spherical magnets is
4.443 cm³ * 250
= 1110.7310 cm³
= 1111 cm³(to nearest cubic cm)
