Answer:
l = 9 cm
b = 7 cm
h = 3 cm
Explanation:
Formula:-
Volume of cuboid = lbh
l - Length of cuboid
b - breadth of cuboid
h - Height of cuboid
To find the dimensions of prism
Here prism is like a cuboid.
Volume of prism = 189 cm^3
Height h = 3 cm
Volume = lbg
189 = l * b* 3
l * b = 189/3 = 63 = 9 * 7
Therefore l and b may be 9 and 7
