Question

Six cubesof length 5 cm are joined end to end. Find the total surface area and the volume of the resulting solid​

Answer 1

Step-by-step explanation:

$a = 6 \times 5 = 30 \: cm$

volume

$v = {a}^{3}$

$= {30}^{3}$

$= 27000 {cm}^{3}$

total surface area is

$tsa = 6 {a}^{2}$

$= 6 \times {30}^{ {}^{2} }$

$6 \times 900$

$= 5400 \: {cm}^{2}$
