Find the TSA of the cuboid whose l=5 dm ,b=15cm and h=2dm
Answers
Answer:
here's ur answer...
given:-
length of the cuboid = 15m
breadth of the cuboid = 6m
height of the cuboid = 5dm
we know that 10dm = 1m
therefore 5dm = 5/10
= 0.5m
→ volume of the cuboid = l×b×h
= 15×6×0.5
= 45m³
→ CSA of the cuboid = 2h(l+b)
= 2×0.5(15+6)
= 1×21
= 21m²
→ TSA of the cuboid = 2(lb+bh+lh)
= 2[(15×6)+(6×0.5)+(15×0.5)]
= 2(90+3+7.5)
= 2×100.5
= 201m²
Step-by-step explanation:
Hope this will help you.
Given :
Length of cuboid (l) = 5 dm => 5dm in cm => 5×10 = 50cm
Breadth of cuboid(b) = 15cm
Height of cuboid (h) = 2dm => 2dm in cm => 2×10 = 20cm
[we converted dm Into cm because breadth of cuboid was in cm amd If we keep different units of dimensions then we can't explain our answer]
To find :
- Total surface area of cuboid ( TSA )
Solution :
We have given Length 50cm, Breadth 15cm and height 20cm, so we can find TSA of this cuboid by given formula :-
Formula using :
TSA of cuboid = 2 ( lb + bh + lh )
Where :-
l = length of cuboid
b = breadth of cuboid
h = height of cuboid
Now, we have formula to find TSA, Let's substitute values in formula :-
Substituting value in formula :
TSA = 2(lb + bh + lh )
=> 2( (50×15) +(15×20)+ ( 50×20)
=> 2 ( 750+ 300+ 1000)
=> 2 ×2050
=> 4100 cm²
