Question

if the length, breadth and height of a cuboid are 15cm , 5cm, 2m respectively.find the volume of a cuboid?​

Answer 1

Length = 15 cm

Breadth = 5cm

Height = 2m

converting m into cm

therefore,

2m = 2×100cm

200cm

now calculate the volume,

Volume of cuboid = l×b×h

volume of cuboid = 15×5×200

volume of cuboid = 15000cm³

hope it helps buddy

Answer 2

Given:

• Length of cuboid = 15 cm
• Breadth of cuboid = 5 cm
• Height of cuboid = 2 m = 2 × 100 = 200 cm

⠀

To find:

• Volume of cuboid?

⠀

Solution:

⠀

$\setlength{\unitlength}{0.75cm}\begin{picture}(12,4)\linethickness{0.3mm}\put(6,6){\line(1,0){5}}\put(6,9){\line(1,0){5}}\put(11,9){\line(0,-1){3}}\put(6,6){\line(0,1){3}}\put(4,7.3){\line(1,0){5}}\put(4,10.3){\line(1,0){5}}\put(9,10.3){\line(0,-1){3}}\put(4,7.3){\line(0,1){3}}\qbezier(6,6)(4,7.3)(4,7.3)\qbezier(6,9)(4,10.2)(4,10.3)\qbezier(11,9)(9.5,10)(9,10.3)\qbezier(11,6)(10,6.6)(9,7.3)\put(8,5.5){\sf{15 cm}}\put(4,6.3){\sf{5 cm}}\put(11.4,7.5){\sf{200 cm}}\end{picture}$

⠀

We know that,

⠀

$\star\;{\boxed{\sf{\purple{Volume_{\;(cuboid)} = l \times b \times h}}}}$

$:\implies\sf 15 \times 5 \times 200$

$:\implies{\boxed{\sf{\pink{15000\;cm^3}}}}\;\bigstar$

$\therefore\;{\underline{\sf{Hence,\;Volume\;of\;cuboid\;is\; \bf{15000\;cm^3}.}}}$

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\qquad\qquad\boxed{\underline{\underline{\bigstar \: \bf\:More\:to\:know\:\bigstar}}}$

• Total surface area of cuboid = 2(lb + bh + hl)

• Curved surface area of cuboid = 2(l + b)h

• Total surface area of cube = 6a²

• Cuved surface area of cube = 4a²

• Volume of cube = a³
