Simple area working out:
Area of a triangle: L x W
———
2
Area of a square: L x W
17 (L) x 17 (H) = 289cm^2
289
——- = 144.5cm^2

There are 4 triangles so:
144.5 x the amount of triangles (4) = 578
Add everything together:
578 + 289 = 867
Answer: 867
Volume = length * width * depth
.. = (3/4 in) * (1/2 in) * (1/4 in)
.. = (3*1*1)/(4*2*4) in^3
.. = 3/32 in^3
