Find the surface area of a rectangular prism with a length of 6.9 mm, a width of 8.2 mm, and a height of 14 mm.

Answer (2)

The answer is 535.96mm squared. To find surface area do length times width plus length times height plus width times height and then you multiply it by 2. You are basically finding the area of all the faces and adding them together.

The surface area of the rectangular prism is calculated using the formula S A = 2 ( lw + l h + w h ) . For the dimensions provided, the total surface area is 537.96 mm². This is found by calculating the area of each face and summing them up before multiplying by 2.
