Find the diagonal of the rectangular prism to the nearest tenth.<br> 4 in<br> 3 in<br> 10 in
hoa [83]

Given:

Consider the dimensions of a rectangular prism are 4 in by 3 in by 10 in.

To find:

The length of the diagonal.

Solution:

Length of diagonal of a rectangular prism is:

d=\sqrt{l^2+b^2+h^2}

Where l is length, b is breadth and h is height.

The dimensions of a rectangular prism are 4 in by 3 in by 10 in. So, the length of diagonal of the rectangular prism is:

d=\sqrt{(4)^2+(3)^2+(10)^2}

d=\sqrt{16+9+100}

d=\sqrt{125}

d=5\sqrt{5}

Approximate the value to the nearest tenth.

d\approx 11.2

Therefore, the length of diagonal of the rectangular prism is 11.2 in.
