If x = 25 units, y = 30 units, z = 6 units, and h = 20 units, then what is the surface area of the triangular prism shown above?

Question

ltrout · Answer

Do you know the formula for the surface area?

ltrout · Answer

The formula is 

SA = wh + lw + lh + ls. 

Using the information you provided:
w = 25
l = 30
s = 6
h = 20

Back to the equation:

Sa = (25)(20) + (30)(25) + (30)(20) + (30)(6) = ?

Can you solve from here?

where is the diagram?

ltrout · Answer

@welshfella I realized that too. But we shouldn't need it since he gave us the sizes?

welshfella · Answer

its a triangular prism  so what exactly does x , y an z mean?

ltrout · Answer

x, y, and z would be the length, width, height I'm assuming.

welshfella · Answer

what is h then?

ltrout · Answer

height

welshfella · Answer

height of what?

welshfella · Answer

you said z = height also

welshfella · Answer

anyway - i guess we'll never know as he's disappeared...

ltrout · Answer

Sorry about that. I'm assuming that x, y, z = length, width, and a side? And then h = height. Could be wrong, but you're right, he's gone.

welshfella · Answer

z could be the height of the triangle and h = height of the prism  but without a diagram we can't be sure
