A candy bar box is in the shape of a triangular prism. The volume of the box is 1,200 cubic centimeters.

Step-by-step explanation:

Given

The dimension of the base is:

See comment for complete question

Required

The height of the base

To do this, we make use of Pythagoras theorem where:

So, we have:

Collect like terms

Take square roots of both sides

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
