Question

if volume of a cube is 729m3 the total surface area of the cuboid formed by joining two such cubes end to end is

Answer 1

Answer:

given : a cube with volume = 729

solution :

volume of cube = side³

729 = side³

³√729 = side

side = 9

case :

if we join 2 cube then

length will be = 9+9=18

width = 9

and height = 9

volume of cuboid = length × width × height

= 18 ×9×9

= 1458

so your answer is = 1458
