Question

Three copper cubes whose edges measure 5cm, 3cm, and 2cm respectively, are melted to form a single cube.Find surface area of new cube..

Answer 1

Answer:

there were 3 cubes if each has 5 ,3 and 2 cm edges so rest of two will also have same edges so,

Step-by-step explanation:

$5 \times 5 \times 5 = 125$

$3 \times 3 \times 3 = 27$

$2 \times 2 \times 2 = 8$

so the edges of new cube is 125,27 and 8

so the formula of surafce area of cube is

a^3

then

$125 \times 27 \times 8 = 2700$

your answer is 2700
