A visually appealing image of a cuboid or rectangular prism with color-coded edges to depict different dimensions. One edge is 6cm long, represented with blue color, another edge that's perpendicular to the first one is 5cm long and represented in green. The third edge, perpendicular to both previous edges, is 7.5cm long and done in red color. The cuboid should be depicted in a three-dimensional manner, and the perspective should highlight the distinct lengths of the edges.

calculate The total surface area of the cuboid of dimension 6cm by 5 by 7.5

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.

What is the surface area of this cuboid with dimensions 6cm, 8cm and 3cm

2(6 * 5) + 2(5 * 7.5) + 2( 6 * 7.5) = ______ square cm

225
