Answer:
502 m²
Step-by-step explanation:
We require to find b before calculating the surface area.
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here V = 510, l = b, b = 10 and h = 3, thus
b × 10 × 3 = 510
30b = 510 ( divide both sides by 30 )
b = 17
--------------------------
The opposite faces of a cuboid are congruent, thus
top/bottom area = 2(17 × 10) = 2 × 170 = 340 m²
front/back area = 2(17 × 3) = 2 × 51 = 102 m²
sides area = 2(10 × 3) = 2 × 30 = 60 m²
Surface area = 340 + 102 + 60 = 502 m²
Answer:
<u>The acceleration is 0.0012 meters/seconds²</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Mass = 250,000 kg
Force = 300 Newtons
2. What is the acceleration?
Based on Newton's Second Law of Motion, let's recall that:
Force = Mass * Acceleration
Acceleration = Force/Mass
Replacing with the real values, we have:
Acceleration = 300/250,0000
Acceleration = 0.0012 meters/seconds² (we can't express acceleration using Newtons/kilograms as the unit).
