How much work is required to lift a 3.7-kg concrete block to a height of 2.7 m?

M g h.

g is the acceleration of gravity
M is the mass
h is the height change

is this correct 9.8*3.7*2.7=97.90

If you put a J (or Joules) after it, then yes

To calculate the work required to lift the concrete block, we will use the formula:

Work = Force × Distance

To begin, we need to determine the force required to lift the block. This force can be found using the equation:

Force = Mass × Acceleration due to gravity

The acceleration due to gravity is approximately 9.8 m/s².

Let's substitute the given values into the equation:

Force = 3.7 kg × 9.8 m/s²

Calculating this gives us:

Force = 36.26 N (rounded to two decimal places)

Now that we have the force required, we can calculate the work by multiplying it by the distance lifted:

Work = 36.26 N × 2.7 m

Calculating this gives us:

Work = 97.96 J (rounded to two decimal places)

Therefore, the work required to lift the 3.7-kg concrete block to a height of 2.7 m is approximately 97.96 Joules.
