Answer:
1 mile/hour is equivalent to 1.47 feet/seconds
Step-by-step explanation:
Given
Required
Determine the equivalent of 1 mile/hour
Express 60 as 60 * 1
Divide both sides by 60
Reorder
Divide 88 by 60
Approximate to 3 significant figures
Hence;
1 mile/hour is equivalent to 1.47 feet/seconds
Answer:
261 cm²
Step-by-step explanation:
To find the surface area of a square pyramid, you must first recognize all of the shapes.
There are four triangles and one square.
The triangles have a base of 9 and a height of 10.
Multiply the product by 1/2.
There are four triangles.
The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.
There square has sides of 9 centimeters.
The area of the square is 81 centimeters.
Lastly, we add the areas of the shapes.
Therefore, the surface area of this square prism is 261 cm².
You can use this layout to find the surface area of a square pyramid.
