Answer:
The length of the diagonal is 8.3
Step-by-step explanation:
The formula for finding the length of the diagonal in rectangular prism is:
d = √[tex](l^{2} + w^{2} + h^{2})[/tex]
"l" represents the length which is 7
"w" represents the width which is 4
"h" represents the width which is 2
Substitute the values to the formula.
d = √([tex]7^{2} ) + (4^{2} ) + (2^{2} )[/tex]
d = √49 + 16 + 4
d = √65 + 4
d = √69
Find the square root of 69 using calculator.
d = 8.30662386292
The direction said round the answer to the nearest tenth. So the answer must be 8.3
