help with my math

OpenStudy (jgkg13):

OpenStudy (welshfella):

volume of the pyramid = (1/3) * area of base * height = (1/3)Ah = 31 Volume of the prism = Ah (1/3) Ah = 31 can you find the value of Ah?

OpenStudy (jgkg13):

15

OpenStudy (welshfella):

just multiply both sides of the equation by 3 and you have it.

OpenStudy (welshfella):

Not 15

OpenStudy (jgkg13):

multiply what

OpenStudy (welshfella):

(1/3)*3Ah = 31*3

OpenStudy (jgkg13):

93

OpenStudy (welshfella):

right volume of prism = Ah = 93

OpenStudy (jgkg13):

46

OpenStudy (welshfella):

??? no the required volume = Ah = 93 mm3

OpenStudy (jgkg13):

i multiplied and got 279

OpenStudy (welshfella):

thats what the question asks for - volume of the prism

OpenStudy (jgkg13):

what

OpenStudy (jgkg13):

you arent explaing it well

OpenStudy (welshfella):

I dont think you are reading it well

OpenStudy (jgkg13):

did i do it right 279 is good

OpenStudy (jgkg13):

or no

OpenStudy (welshfella):

as i've said already The volume of the prism = Ah (area * height) the volume of the triangular pyramid = (1/3) Ah and its volume is given as 31 mm3 So (1/3) Ah = 31 now to get the value of Ah ( the volume of the prism) you multiply both sides of the equation by 3 which gives you Ah = 31*3

OpenStudy (welshfella):

I can't be clearer than that.

OpenStudy (jgkg13):

93

OpenStudy (jgkg13):

so the answer would be 31 times 9 wich gives me 93 right

OpenStudy (welshfella):

31 * 3 = 93mm3

OpenStudy (jgkg13):

thats the answer to my problem

OpenStudy (welshfella):

yes

OpenStudy (jgkg13):

thank you
