Answer:
150.88
Step-by-step explanation:
Side lengths are 7.4 ,3.1 and 5
How i do it is do all the combinations so 7.4 x 3.1 = 22.94
5 x 3.1 = 15.5 and 7.4 x 5 = 37
then add them all up 22.94 + 15.5 = 38.44 + 37 = 75.44
Now double it since there is two heights, two lengths and two widths
75.44 x 2 = 150.88
If you think there are 4 heights and lengths and widths we already included all numbers twice so just double it
Answer:
Total surface area of the rectangular prism is 150.88 cm^2
Step-by-step explanation:
area of base = area of top
area of base = 5 x 3.1 = 15.5 cm^2
Area of small lateral surface having dimensions 3.1 cm x 7.4 cm is
=3.1 x 7.4 = 22.94 cm^2
Area of big lateral surface having dimensions 5 cm x 7.4 cm is
=5 x 7.4 = 37 cm^2
Total area of prism = 2 x 15.5 + 2 x 22.94 + 2 x 37 = 150.88 cm^2
total surface area of the rectangular prism is 150.88 cm^2
