Answer» Answer: 51300 Step-by-step explanation: lateral surface AREA of CUBOID= 2(l+b)h Area of five sides,as ROOF is excluded 2(l+b)h + lb =2(50+30)2.5 + 30×50 =400+1500 =1900 rate of cementing the floor is 27 per sq.m =1900 x 27 =51300

Answer»

Answer:

51300

Step-by-step explanation:

lateral surface AREA of CUBOID= 2(l+b)h

Area of five sides,as ROOF is excluded

2(l+b)h + lb

=2(50+30)2.5 + 30×50

=400+1500

=1900

rate of cementing the floor is 27 per sq.m

=1900 x 27

=51300
