Answer 1

Surface area of a square prism = 2a^2 + 4ah

Answer 2

Volume of a square prism = a^2h

Answer 3

so 2*Area^2+4*area*height?

Answer 4

No a is the base edge

Answer 5

Ok so:
2*6^2+4*6*3?

Answer 6

yup

Answer 7

Which equals 216?

Answer 8

no 144 lol

Answer 9

I'm doing a bad job at explaining this : / ?

Answer 10

Um, not really, Im just having a hard time understanding

Answer 11

Like, I see teh formula, but its just not clicking.
Thats just me and math XD

Answer 12

Let me see if @jim_thompson5910 can explain better for me

Answer 13

Or @campbell_st

Answer 14

Ok :)

Answer 15

ok so what did you get for the surface area of the solid... and what did you get for the volume of the solid...?

Answer 16

@capmbell_st
I got SA = 216
and
V = 270?

Answer 17

@iPwnBunnies

Answer 18

ok... the question is asking for the ratio

surface area : Volume

216 : 270

simplfy the ratio...

if you are writing it as a fraction its 216/270

Answer 19

@And then to get it as a decimal you divide the numerator by the denominator?

Answer 20

@campbell_st

Answer 21

divide them both by 3

72: 81

divide them both my 9

8 : 9

thats the answer
