the length,breadth and height of a cuboid are 3cm,4cm and 5cm respectively.find its total surface area,volume and the length of diagonal.
Answers
Step-by-step explanation:
given,
length=3cm
breadth=4cm
height=5cm
TOTAL SURFACE AREA OF CUBOID
=2(lb+bh+hl)
=2(3×4 +4×5 +5×3)
=2(12+20+15)
=2(22+15)
=2(37)
TSA =74
VOLUME OF CUBOID=L×B×H
=3×4×5
=12×5
=60
Given:
Length of cuboid (l) = 3cm
Breadth of cuboid (b) = 4cm
Height of cuboid (h) = 5cm
To Find:
The surface area, volume, and length of the diagonal of the cuboid.
Solution:
The surface area of cuboid = 2lb + 2 lh + 2hb = 2(12+15+20) cm² = 94cm²
The volume of cuboid = length × breadth × height = (3×4×5) cm³ = 60 cm³
The length of diagonal of a cuboid = √(l²+b²+h²) = √(9+16+25) = 5√2 cm
Hence, the total surface area, volume, and length of diagonal of the cuboid is 94cm², 60cm³, and 5√2cm respectively.
