Abrick has a base area of 38 1/4 square inches and a height of 2 1/2 inches. what is the volume of the brick?

Step-by-step explanation:

we know that

The volume of a brick is equal to

where

B is the area of the base of the brick

h is the height of the brick

In this problem we have

Convert to an improper fractions

substitute the values

convert to mixed number

multiply the base area by the height

38 1/4 x 2 1/2  = 95 5/8 cubic inches

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

207/8 is the right
