The total surface area of a cuboid is given by the formula:
SA = 2lw + 2lh + 2wh
Where:
l = length
w = width
h = height
Substituting the given values:
SA = 2(6 x 5) + 2(6 x 7.5) + 2(5 x 7.5)
SA = 60 + 90 + 75
SA = 225
Therefore, the total surface area of the given cuboid is 225 m².
Calculate the total surface area of the cuboid of dimensions 6m by 5m by 7.5m
