Question

Tanner calculates the volume of a rectangular prism with dimensions ft by 5 ft by ft. His work is shown below.

Answer 1

Answer:

He multiplied the denominators incorrectly

(COMPLETING THE MISSING PARTS OF THE QUESTION)

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?

Solving the Question:

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:

$V = \frac{3}{4}\cdot\frac{5}{1}\cdot\frac{1}{2}\\\\V=\frac{3\cdot5\cdot1}{4\cdot1\cdot2}\\\\V=\frac{15}{8}\\V=1.875$

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