Question

Alka places five ice cubes from the freezer, each of sides 5 centimetres each adjacent to each other. find the area of the resultant cuboid that gets formed?

Answer 1

Surface area=2*(5*5)+2*(5*25)+2*(5*25)=50+250+250=550cm²

Answer 2

Answer:

The surface area of the resulting cuboid is 530 centimeter square.

Step-by-step explanation:

Given : Alka places five ice cubes from the freezer, each of sides 5 centimeters each adjacent to each other.

To find : The area of the resultant cuboid that gets formed?

Solution :

Each side of the cube is 5 cm.

When five cuboid are joined end to end, then the resulting solid is a cuboid.

Length of the cuboid, l = 5× each side of the cube = 5 × 5 cm = 25 cm

Breadth of the cuboid, b = each side of the cube =5 cm

Height of the cuboid, h = each side of the cube = 5 cm

Surface area of the cuboid

$SA=2(lb+bh+hl)$

$SA=2(25\times 5+5\times 5+5\times 25)$

$SA=2(125+25+125)$

$SA=2(275)$

$SA=530$

Thus, The surface area of the resulting cuboid is 530 centimeter square.
