    Answer:

    The work done is 2.94 Nm.

    Explanation:

    First, you have to find the force of a brick layer using the formula, Force = mass×gravity :

    f = m \times g

    let \: m = 10,g = 9.8

    f = 10 \times 9.8

    f = 98N

    Given that the force of a brick layer is 98N. Next, you have to apply work done formula, Work done = force×distance :

    w.d = f \times d

    let \: f = 98,d = 0.03m

    w.d = 98 \times 0.03

    w.d = 2.94Nm
