Question

22) Find the surface area of the rectangular prism.

Answer 1

`\huge\boxed{\sf 208\ cm\²}`

Explanation:

This rectangular prism is made up of 6 rectangles.

Area of rectangle:

• Area = length × width

Solution:

Now, finding the areas.

Top rectangle:

= 4 × 8

= 32 cm²

Middle rectangle:

= 8 × 6

= 48 cm²

Side rectangles:

= 2(length × width)

= 2(6 × 4)

= 2(24)

= 48 cm²

Above the bottom rectangle:

= 4 × 8

= 32 cm²

Bottom rectangle:

= 8 × 6

= 48 cm²

So,

Add up all of them to get the surface area of the prism.

Surface Area:

= 32 + 48 + 48 + 32 + 48

= 208 cm²
