a rectangle prism has a length of 5/8 inch and a width of 7/9 inch. The volume of the prism is 7/8 cubic inch. Find the height of the prism. Write your answer as a fraction or mixed number in simplest form.

Respuesta :

Using the volume formula: volume = length x width x height

You are given volume , length and width:

7/8 = 5/8 x 7/9 x height

Multiply length x width:

7/8 = 35/72 x height

Solve for height by dividing both sides by 35/72

Height = 7/8 / 35/72

Height = 9/5 inches = 1 4/5 inches

Step-by-step explanation:

In the question it gives that a rectangle prism has a length of 5/8 inch and a width of 7/9 inch. The volume of the prism is 7/8 cubic inch.

we have to find the value of height of the prism

As we know that

[tex]\pmb{\boxed{Volume=length ×width ×height }}[/tex]

According to the question,

[tex]\dfrac{7}{8}=\dfrac{5}{8}×\dfrac{7}{9}×height \\\\\dfrac{7}{8}=\dfrac{35}{72}×height\\\\height=\dfrac{7}{8}×\dfrac{72}{35}\\\\\bold{height=\dfrac{9}{5}=1\frac{4}{5}}[/tex]
