Question

what is the surface area of the four walls of the water tank if its length is 8 feet with 5 feet and height 5 feet​

Answer 1

Answer:

130ft²

Step-by-step explanation:

length is 8 feet

width is 5 feet

height is 5 feet

2(l+w)h

=2(8+5)5

=2×13×5

=10×13

=130

Answer 2

length is 8 feet

width is 5 feet

height is 5 feet

Area of 4 walls = 2(length + width ) × height.

so,

$2(l + w)h \\ = 2(8 + 5)5 \\ = 2 \times 13 \times 5 \\ = 10 \times 13 \\ = 130$

so, the area of 4 walls is 130 sq. feet

Hope this helps you.
