Answer:
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
