Question

Two metallic cube of 9cm each are jouned side to side. Find volume and lateral surface area of new figure formed.​

Answer 1

Step-by-step explanation:

the new figure that is cuboid

so the lenght= 2*9=18cm

and height and breadht are 9 cm

so volume of cuboid=l * b * h

= 18*9*9

=1458cm^3

and the lateral surface area =2(l+b)*h

=2(18+9)*9

=2*27*9

=486cm^2

Answer 2

Answer:

V=1458 cm³ and

A=486 cm³

Step-by-step explanation:

Given,

Side of a metallic cube is 9 cm.

If two cube joined side by side the form a cuboid.

Dimension of cuboid

length =$l=2a=2\times 9=18$cm

breadth=$b=a=9$cm

height=$h=a=9$cm

Volume of cuboid=length× breadth× height

$V=l\times b\times h$

$=18\times 9\times 9$

$V=1458$cm³

Lateral surface area of cuboid

$A=2\left ( l+b \right )h$

$=2\left ( 18+9 \right )9$

$=2\times 27\times 9$

$A=486$cm³
