Question

Please help and explain with the work that comes with it

Answer 1

V = l * w * h

l = 5 1/4

W = 3 1/2

H = 4

$\test{V} = \dfrac{21}{4} * \dfrac{4}{1} * \dfrac{7}{2} = \dfrac{147}{2} = 73 \dfrac{1}{2} \text{ Answer}$

Notes

1. I've used 4/1 rather than 4 as one of the dimensions. 4/1 is easier to see

2. The 4s cancel in the first step. That makes both the numerator and denominator easier to read.]

3. In decimal form the answer is 73.5
