Answer question no.10​

Answer 1

Answer:

$1000cm^{2}$

Step-by-step explanation:

edge= 10 cm

after joining we get cuboid

l=10

b=20

h=10

tsa=2(lb+bh+hl)

=2(200+200+100)

=2(500)

=$1000cm^{2}$

Answer 2

Answer:

When edge of 10 cm Cube join together the dimensions of formed cuboid are

@Length (l) = 20 cm

@Breadth(b)=10 cm

@Height (h)=10 cm

______________________________________________________________

Total Surface Area Of cuboid = 2(lb+bh+hl)

= 2(20X10+10X10+10X20)

= 2(200+100+200)

= 2(500)

= 1000 cm²
