W=FS

W=mgS

total displacement= (50×25)cm=1250cm=12.5m

therefore total work done

W=(25×10×12.5)joule. (g=10m/s²)

W=3125joule

I know it will help

so mark me brainliest

ANSWER :

Mass of block (m) = 25kg

Height (h) = 25×25 = 625cm

Work done W = mgh

= 25×10×625

W = 43620 J

Mark me as brainlist and this tym please don't report it.... .......

it is the correct answer
