The surface area of the given two rectangular prism is given as follows:
498 cm².
What is the surface area of a rectangular prism?
The surface area of a rectangular prism of length l, width w and height h is given as follows:
S = 2(lw + wh + hl).
For this problem, there are two prisms, with dimensions given as follows:
- l = 12 cm, w = 7 cm, h = 7 cm.
- l = 2 cm, w = 7 cm, h = 2 cm.
Hence the surface area of the figure is the combined surface area of each figure, hence:
S = 2(7 x 7 + 12 x 7 + 12 x 7) + 2(2 x 7 + 2 x 2 + 7 x 2) = 498 cm².
