Explanation:
3.1.1 The base of the prism is a rectangle.we know this by checking the properties of the base,that is, opposite side are equal and it has all angles equal to 90°
3.1.2the area of a rectangle is calculated using the formula: A=LxB
where: A is the Area
L is the Length of the shape
B is the breadth
3.1.3 to calculate the volume of a prism we can use the formula V=A(base)xh
where:V is the volume
A is the area of the base
h is the height of the prism
3.1.4V=Axh
=(LxB)xh
=(140mm x 115mm)x 125mm
=2012500mm³
