The picture shows a rectangular prism with
A length of 15mm
A width of 3mm
And a Height of 4mm
What is the surface area of the prism?
Surface Area = 2(Length x Width) + 2(Length x Height) + 2(Width x Height)
Surface Area = 2(15mm x 3mm) + 2(15mm x 4mm) + 2(3mm x 4mm)
Surface Area = 90mm + 120mm + 24mm
Surface Area = 234mm
