Best ResponseYou've already chosen the best response.0volume of a prism = area of base x height so plug in your 2 values and solve the equation

Best ResponseYou've already chosen the best response.0i assume that the prism is standing on its end!

Best ResponseYou've already chosen the best response.0if the base of a right prism is a rhombus with diagonals 10 in and 12 in and the volume of the prism is 60 cu in find the height of the prism please help!

Best ResponseYou've already chosen the best response.0well we usually talk about the length and cross sectional area of a prism. I prism is a 3 dimensional object with a uniform cross section  a bit like a toblerone bar of chocolate

Best ResponseYou've already chosen the best response.0ok . could you please explain to me how to solve the problem

Best ResponseYou've already chosen the best response.0well assume the prism is resting on its base which is a rhombus then its volume = area of the rhombus x the height so 60 = area of rhombus x h so we need to calculate the area of the rhombus

Best ResponseYou've already chosen the best response.0ok so its going to be d1d2 divided by 2 to solve for area

Best ResponseYou've already chosen the best response.0heck! is that the area of a rhombus  you've got that from a maths book or by other means??

Best ResponseYou've already chosen the best response.0other means but when i calulate it it comes out to 60 = 60

Best ResponseYou've already chosen the best response.0well d1d2 /2 = 30/2 = 15 so qwe have 60 = 15 x h h = 4 height is 4

Best ResponseYou've already chosen the best response.0sorry  i must be tired its 12 x 10 divided by 2 giving 60  either the d1d2 formula is wrong or volume = 60 is wrong. hold on and i'll check my maths stuff

Best ResponseYou've already chosen the best response.0ok  the volume d1d2/2 is correct so the answer must be h = 1 60 = 60 x h h=1

Best ResponseYou've already chosen the best response.0lol  thats wrong because the diagonals are in inches and the volume is in cubic feet right 60 cu feet = 60 x 12^3 cu ins = 103680 cu ins so 103680 = 60 x h h = 12^3 = 1728 ins or 144 ft

Best ResponseYou've already chosen the best response.0well the volume is 60 cu ft isn't it

Best ResponseYou've already chosen the best response.0i 'm going crazy  i've just checked your earlier post  its 60 cu ins there

anonymous

Best ResponseYou've already chosen the best response.0in which case h = 1 inch as i said earlier

Best ResponseYou've already chosen the best response.0ok so the diagonal of a cube is 7\[\sqrt{3}\] find the voulme of the cube

anonymous

Best ResponseYou've already chosen the best response.0i assume you mean the diagonal of one side of the cube. by pythagoras (7sqrt3)^2 = 2x^2 (where x = one side of cube) 147 = 2x^2 x = sqrt(147/2) = 8.5732 vlume of cube = (8.5732)^3 = 630.13 correct to 2 dec places
