If l=5 cm , b=6 cm and h = 5 then TSA of cuboid is
20 points

170cm²

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cuboid.

Given data

Length l=5 cm ,

Breath b=6 cm and

Height h = 5

We know that the total surface area of a cuboid is expressed as

SA=2lb+2lh+2hb

SA= 2(5*6)+ 2(5*5)+2(5*6)

SA= 2*30+2*25+2*30

SA= 60+50+60

SA= 170cm²

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

i believe the correct answer is b.
