Answer

Given

Mass (m) = 10 kg

No. of stairs = 20

Height (h) = 20 cm

Width (b) = 15 cm

g = 10 m/s²

Notice that all the units are not in SI system so,

h = 20 cm

➡ h = 20/100 m

➡ h = 0.2 m

Solution

Work done = mgh

➡ Work done = 10 × 10 × 0.2

➡ Work done = 20 J

Total work done = 20 × 20 ( Work done × no. of stairs )

Total work done = 400 J

\huge\mathrm{Note}

⭐ Width is just given for confusion

⭐ Apply the formula of work done

⭐ And then multiply it with the number of stairs to find the overall total work done
