To calculate the total surface area of a cuboid, you need to add up the areas of all its six faces.
The formula for the total surface area (TSA) of a cuboid is:
TSA = 2(lw + lh + wh)
Given the dimensions of the cuboid as follows:
Length (l) = 6 cm
Width (w) = 5 cm
Height (h) = 7.5 cm
Substituting these values into the formula, we can calculate the total surface area as follows:
TSA = 2(6 * 5 + 6 * 7.5 + 5 * 7.5)
TSA = 2(30 + 45 + 37.5)
TSA = 2(112.5)
TSA = 225 cm^2
So, the total surface area of the given cuboid is 225 cm^2.
