Tanner calculates the volume of a rectangular prism with dimensions ft by 5 ft by ft. His work is shown below. What error did Tanner make?

He multiplied the numerators incorrectly.

He multiplied the denominators incorrectly.

He simplified incorrectly.

He wrote 5 as a fraction incorrectly.

He multiplied the denominators incorrectly

Tanner calculates the volume of a rectangular prism with dimensions of three by four feet by five feet by one half feet.

His work is shown below:

V = L.W.H

V = (3/4)(5/1)(1/2) = ((3)(5)(1)) / ((4)(1)(2)) = 15/6 = 2.5

What error did Tanner Make?

We know that volume is given by:

V = L.W.H

where

L = 3/4 ft

W = 5/1 ft

H = 1/2 ft

Find V:

As the product of denominators is 8, not 6 as to per Tanner's calculations, he multiplied the denominators wrong

answer: 1, 3 and 5 are correct
