Asandbox must be filled with sand. the sandbox has a depth of 2ft and a diameter of 14 ft. how much sand to fill the sandbox

First you have to find the volume. the formula for volume is L x W x H. the length and with are the same. idk if you have to multiply 14 x 14. that is 196. 196 x 2= whatever the equals and that should be yo answer.

you can't solve x because it is 2 linear equation and you only have one equation
