Answer:
a) 72cm^3 b) 18 (2 x 2 cm)cubes
Explanation:
Cm cube = 4/1 x 18 = 72cm^3
(The reason we call this cube ^3 is because the cubes are cube 3D shape, if they were just large blocks they will still be called cube as they are 3D only the metric changes if they are much bigger or much smaller.
Mass Density for example is measured in km/m
Cube smaller shapes and polygons that fit with geometry are measured in cm usually occasionally inches.
Here are the workings for Volume
a)
1) Find the Rectangle face measures. = 6 x 4 = Area first.
2) Then find the depth and multiply it with Area = 24 x 3 = V
=Volume = 72cm^3
b) How many 2 x 2 cm cube can we find? 72/4 = 18 square cm cubes are n the rectangular cuboid.
