Answer» Vol. of wooden plank= l×b×h........ ... b= 3m.........., h= 75 cm=0.75m...... So, l×b×h= 33.75.............. l×3×0.75=33.75.......... l = 33.75/3×0.75......=45/3=15....... So length= 15m................ Now TSA of wooden plank = 2(lb+bh+hl)........= 2( 15×3+3×0.75+0.75×15).........=2( 45+2.25+11.25).........= 2( 58.5)...= 117m^2... please like the solution 👍 ✔️ |
