@butterflydreamer

Answer 1

okayy so first step would be to find the total volume of the eight spheres.

Answer 2

so i find V of one sphere and then times 8 it?

Answer 3

V = volume

Answer 4

yyep!

Answer 5

wait lemme calculate

Answer 6

\[4/3 \times 22/7 \times 8? \]

Answer 7

mmm.. .you forgot the r^2.
So V= 4/3* pi *r ^2

Answer 8

hmm?
i thought its r^3?

Answer 9

oh yeah LOL my bad!
V = 4/3* pi * r^3
Then multiply that by 8

Answer 10

4/3*22/7*64*8?

Answer 11

2145.52 TIMES 8?

Answer 12

.................. no
