Answer:

255 steps

Step-by-step explanation:

They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:

140m * 100cm / 1m = 14000

Therefore the bridge would have a length of 14000 centimeters, we divide:

14000/55 = 254.54

Which means that Robert take at least 255 steps to fully walk the bridge.

Answer: this is from my knowledge.. but no I think this is not true?

Step-by-step explanation:

this is the equation for surface area: SA = 6 × a^2

and I'm certian that the a variable is used for the number being multipled into the sides (if that makes sense.) so If we replace a with 3 the equation is:

<h3>SA = 6 × 3^2</h3><h3 /><h3>which is definetly more than 6. </h3><h3 /><h3>So I'm betting the answer is: False.</h3><h3 /><h3>I hope you don't mind the long explanation, I just wanted you to understand how I got my answer, I'm also in-experinced in this field, so if it is incorrect 100% my fault :(</h3>
