where slope, m= -3/2 and intercept, c = 7
There are 60 cubic units in the provided three-dimensional figure, and the units are mm³, cm³, and m³.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
We have a three-dimensional shape shown in the picture with dimensions.
The total cubic units = 4×3×5 = 60 cubic cm
We can measure the volume with units of mm³, cm³, m³, km³
We can draw a relation between them:
mm³<cm³ <m³< km³
For the first picture, the unit mm³ would be best for measuring the volume.
For the second picture, the unit cm³ would be best for measuring the volume.
For the third picture, the unit m³ would be best for measuring the volume.
Thus, there are 60 cubic units in the provided three-dimensional figure, and the units are mm³, cm³, and m³.
