first calculate the T.S.A=2 [LB+BH+HL]
=2 [80×30+30×40+80×40]
=2 [240+120+320]
=2 [680]
=1360cm^2
Are of Front Face=L×H
=80×40=320cm^2
Area of top face=L×B
=80×30
=240cm^2
Area of Front and top face=240+320=560cm^2
Area Remaining=1360-560=800cm^2
You Answer IS 800cm^2

Answer:
here it is
Step-by-step explanation:
ANSWER
The dimensions of cuboid are 50×40×25
The Lateral surface area of cuboid is given by 2h(l+b)
Here l=50;b=40;h=25
Lateral surface area is 2×25(50+40)=50(90)=4500
And the base area is given by lb=(40)(50)=2000
So The total area is given by 4500+2000=6500
