Total perimeter is 522 ft. I will guess the gym is a big rectangle.
Therefore, Perimeter of a rectangle = 2L + 2W
P= 2L+ 2W
We know 80 ft wide. so now we plug and chug the equation we came up with
P=522 ft
P=2L+ 2(80)
522=2L+ 160
L= 181

Answer:
<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>
Step-by-step explanation:
To find the mass in kg we must first convert the density from g/cm³ to kg/m³
That's 7.5 g/cm³ = 7500kg/m³
Density = mass / volume
Volume of block = 1.5 × 0.4 × 0.25
= 0.15m³
mass = Density × volume
= 7500 × 0.15
<h3>= 1125 Kg</h3>
