A cubiod has a lenght 13cm wit 9cm and height 8cm calculate surrface area

To calculate the surface area of a cuboid, you need to find the areas of all its six faces and then add them together. The formula for the surface area of a cuboid is:

Surface Area = 2(Length × Width + Length × Height + Width × Height)

Let's calculate the surface area of the given cuboid:

Length = 13 cm
Width = 9 cm
Height = 8 cm

Surface Area = 2(13 × 9 + 13 × 8 + 9 × 8)

First, multiply the length and width: 13 × 9 = 117 cm²

Second, multiply the length and height: 13 × 8 = 104 cm²

Third, multiply the width and height: 9 × 8 = 72 cm²

Now, substitute these values back into the formula:

Surface Area = 2(117 + 104 + 72)

Next, add the three products together: 117 + 104 + 72 = 293 cm²

Finally, multiply the sum by 2: 2 × 293 = 586 cm²

Therefore, the surface area of the given cuboid is 586 cm².
