Assuming you mean the total surface area of the cuboid with measurements 5m x 3m x 2m:
There are 6 faces, the opposite pairs of which are the same size, making 3 different face sizes; so double the area of the three different faces:
Surface_area = 2 x (5 m x 3 m + 5 m x 2 m + 3 m x 2 m)
= 2 x (15 m2 + 10 m2 + 6 m2)
= 62 m2
3m x 2m = 6 m2
6m
2m by 3m is 6 m2.
74 square metres.
m(3m + 2)
2m by 3m is 64.58 square feet.
3m x 2m = 6 m2
6m
2m by 3m is 6 m2.
3m*3m*2m=300*300*200=18,000,000cm3
2m + 2 = 3m + 4 => 2m-3m = 4-2 => -m = 2 => m= -2
74 square metres.
m(3m + 2)
-3m
n-2m
5m+3=3m+9 5m+3-3=3m+9-3 5m=3m+6 5m-3m=3m+6-3m 2m=6 (2m)/2=6/2 m=3
200cm = 2m ...
