answer not getting can any one help me out
Answers
Step-by-step explanation:
T.S.A.= (a) 2(5.5 + 4000+ 1500)= 5505.5(2) = 11011 cm^2
(b) 2(5500 +25 + 7500) = 13025(2) = 26050 cm^2
L.S.A.= (a) 2 x 5.5 (4000+1500) = 11 x 5500 = 60500 cm^2
(b) 2 x 25 (5500+7500) = 50 x 1300 = 65000 cm^2
HOPE IT HELPS YOU PLEASE MARK AS BRAINLIEST.
MUCH HARDWORK DONE ON THIS.
Answer:
Step-by-step explanation:
(1) l=5.5 cm=0.055m
b=4m
h=1.5 m
Lateral surface area of a cuboid=2(l+b)h
=2(0.055+4)×1.5
=2(4.055)×1.5
=3.0×4.055
=3×4.055
. =12.165 m^2
Total surface area of a cuboid=2(lb+bh+hl)
=2(0.055×4+4×1.5+1.5×0.055)
=2(0.22+6+0.0825)
=2×6.3025
=12.605m^2
(2)l=5.5m,b=25cm=0.25m and h=75000mm=75m
Lateral surface area of cuboid=2(l+b)h
=>2(5.5+0.25)×75
=>2(5.75)×75
=>150×5.75
=>862.5m^2
Total surface area=2(lb+bh+hl)
=>2(5.5×0.25+0.25×75+75×5.5)
=>2(1.375+18.75+412.5)
=>2×432.625
=>865.25m^2
