Question

1. which describes the combined variation in the formula $v = lwh$?

$\bigcirc$ $v$ varies jointly with $l$, $w$, and $h$

$\bigcirc$ $v$ varies inversely with $l$, $w$, and $h$

$\bigcirc$ $v$ varies jointly with $l$ and $h$

$\bigcirc$ $v$ varies directly with $w$ and $h$

Explanation:

The formula \( V = \ell wh \) shows that the volume \( V \) depends on the product of length \( \ell \), width \( w \), and height \( h \). When a quantity varies jointly with multiple variables, it means it is directly proportional to their product, which matches this relationship. The other options either exclude variables or incorrectly state inverse variation.

Answer:

V varies jointly with ℓ, w, and h
