My best guess is that you're looking for the volume or perimeter of a pyramid.
Lets first solve for volume:
V=1/3 (A * H)
, where A is the area of the base and H is the height.
The area of a triangle can be found using 1/2(s1*s2)
A=1/2(10cmx12cm)
A=1/2(120cm^2)
A=60cm^2
Now we can solve for volume
V=1/3(60cm^2*17cm)
V=340cm^3
Volume is 340 centimeters cubed
The Surface area of a triangular pyramid is
3(1/2WH)+A
after working this out I got
476 cm squared
