Find the volume , including units of a square pyramid with base length 5 cm and height 6cm

Mathematics
1 answer:
VARVARA [1.3K]2 years ago
8 0

Answer:

50 cm^2

Step-by-step explanation:

The volume of a square pyramid can be found using:

v= 1/3 bh

Where b is the area of the base, and h is the height

First, we have to find the area of the base

a=l*w

In a square, all sides are equal, so we know the length and the width are both 5

a=5*5

a=25

Now, we can substitute 25 in for b, and 6 in for h

v=1/3bh

v=1/3(25*6)

v=1/3(150)

v=50

Volume uses units cubed, and in this case our units are centimeters

The volume is 50 cm^3

The BJ Electrical Company needs to hire master electricians and apprentices for a one week project. Master electricians receive
Stells [14]

Answer:

The BJ Electrical Company

The BJ Electrical Company should hire:

8 master electricians and

22 apprentices

in order to accomplish the project and still meet the contract safety requirements.

Step-by-step explanation:

Number of workers needed = 30

Class of workers:

Master electrician, with per week salary = $750 per worker

Apprentices, with per week salary = $350 per worker

Number of inspection hours required from each master electrician = 3 hours

Total inspection hours for the project = 25 hours

Average number of master electricians needed = 25/3 = 8.333 = 8

Number of each type of worker needed:

Master electricians = 8

Apprentices = 22 (30 - 8)

Cost to be incurred for workers:

Master electricians = $6,000 (8 * $750)

Apprentices =               7,700 (22 * $350)

Total labor cost =      $13,700
