Question

1. What will be the total surface area of this larger cube?
The cube shown above has a volume of 8 cm. Eight such cubes were joined to form a me
cube shown here.
a. 96 cm
b. 64 cm
C. 16 cm
d. 24 cm​

Answer 1

Answer:

Option A is correct.

Step-by-step explanation:

Given:

Volume of the smaller cubes = 8 cm³

Larger cube is formed by joining 8 smaller cubes.

To find: Total Surface Area of the larger cube.

Volume of the larger cube =  8 × volume of smaller cubes = 8 × 8 = 64 cm³

Volume of cube = (side)³

Side of larger cube = x

⇒ x³ = 64

x = ∛64

x = 4 cm

Total surface area of the larger cube = 6 × side² = 6 × 4² = 96 cm²

Therefore, Option A is correct.

Answer 2

Answer:

a is correct

Step-by-step explanation:

smaller cubes or sc is 8

v =of l.c 8

side of l.c =x^3=64

x is 4
