Question

1. If two cubes each of side 5 cm are joined face to face,
then find the volume of the resulting cuboid.
- 125 cu cm
b) 250 cu cm
c) 136 cu cm
​

Answer 1

Answer:

Use the formula and calculate

Answer 2

$Given \: each \:side \: of \: two \: cubes(a) = 5 \:cm$

/* If two cubes joined face to face , we get a cuboid */

$\underline{\pink{ Dimensions \:of \: a \:cuboid }}$

$Let \: length (l) = 2a ,$

$breadth (b) = a , \: and \: height (h) = a$

$Volume \: of \: the \: Cubiod$

$= l \times b \times h$

$= 2a \times a \times a$

$= 2a^{3}$

$= 2 \times 5^{3}$

$= 2 \times 125$

$= 250 \: cubic \:cm$

Therefore.,

$Option \: \green { ( b ) } \:is \: correct$
