To find the volume, we should find the area of the triangle, the multiply by the depth of the object.
Area of Triangle = 1/2 * base * height = 5.7cm * 7.6cm / 2 = 21.66cm^2
Multiplying this by the depth of the object and we find:
21.66cm^2 * 4.8cm = 103.968cm^3
which we can round (if needed) to 103.97cm^3
