A right rectangular prism has base dimensions of 2 1 /10 ft wide and 4 1/ 5 ft long. If the height of the prism is 3 1 /2 ft, what is the volume of the prism?

2 1/10 x 4 1/5 x 3 1/2 = 30 87/100 feet

(Remember multiply one by one first multiply 2 1/10 x 4 1/5 = 8 41/50

then multiply 8 41/50 with 3 1/2 to get = 30 87/100 is your answer)

Step-by-step explanation:

Just multiply the given lengths. A 3 dimensional shape has to be given 3 sides in order to know the area/volume: Length x Width x Height

what is the original number? you forgot to add it.
