Asmall bar of gold measures 40 mm by 25 mm by 2 mm. one cubic millimeter of gold weighs about 0.0005 ounces. find the volume in cubic millimeters and the weight in ounces of this small bar of gold.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: just subtact the units and then add the non negative : happy to
