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.

What is the volume of this rectangular prism? <br> 3ft by 6 1/4 ft by 14 ft
Liula [17]
We can find the volume of any rectangular prism by simply multiplicating its height, length and width.

Also, lets change that 6 1/4 to 6.25, or 25/4 if you like. I’m gonna use 6.25.

If we take volume as “V”, then:

V = L * W * H
V = 3ft * 6.25ft * 14ft
V = 262.5 ft^3 (Its ft cubed because we multiplied by ft three times.)
