Q.3 Find the TSA of cuboid of length 30cm, breadth 25cm and height 20 cm
Answers
Answer:The volume of cuboid is 15000 cm³
The surface area of cuboid is 3700 cm²
The lateral surface area of cuboid is 2500 cm²
The length of body diagonal of cuboid is 43.87 cm
Step-by-step explanation:
A cuboid whose length breadth and height are 30 cm ,20 cm,25 cm respectively.
Length, l = 30 cm
Breadth, b = 20 cm
Height, h = 25 cm
Volume of cuboid, V = lbh
V = 30×20×25
V = 15000 cm³
Surface area of cuboid, S = 2(lb + bh + lh)
S = 2(30×20 + 30×25 + 25×20)
S = 3700 cm²
Lateral surface area of cuboid, L = 2h(l+b)
L = 2×25 (30+20)
L = 2500 cm²
Length of body diagonal of cuboid, D=\sqrt{l^2+b^2+h^2}D=l2+b2+h2
D=\sqrt{30^2+20^2+25^2}D=302+202+252
D=43.87\ cmD=43.87 cm

hope this helps mark me as brilliant
Answer:
formula=2×(lb+bh+hl)
=2×(30×25+25×20+20×30)
=2×(750+500+600)
=2×(1850)
=3700cm2
