Question

The total surface area of the cuboid formed when two cubes each of edge ‘l’ are joined end to end is __________

Answer 1

Answer:

I think the total surface area of the cuboid formed when two cubes each of edge ‘l’ are joined end to end is 10l²

Step-by-step explanation:

in a cube, all surfaces are square and the length of each edge is same. If each edge is denoted by 'l', then area of each surface is l². In a cube there are 6 Edges thus 6 l² , 6 l² + 6 l²= 12 l² - 2 l²= 10 l². -2 l² because 2 surfaces are joined and merged to form cuboid.

This was my first answer, pls correct me if im wrong

thanks

Answer 2

Answer:

The cuboid generated when two cubes with edge types of "l" are linked end to end has a total surface area of 10i².

Step-by-step explanation:

What is the surface area of cuboid?

• A three-dimensional shape's surface area is the total area on its surface. Add the areas of each of the six rectangular sides of a cuboid to determine its surface area.

We have two side A cubes.

When these two cubes are united face-to-face, a cuboid is formed that has twice the length of a cube in length and the same width and height as the combined cubes.

For example, l = 2i, b = i, and h = i

The cuboid's total surface area is therefore equal to 2(l b + b h + h l).

= 2(2i x i + i × i + i × 2i)

= 2(2i² + i² + 2i²)

= 2 x 5i²

= 10i²
