Answer:

15 students

Step-by-step explanation:

25% = 1/4, so you can just do 1/4 of 60 or 1/4 * 60. 60/4 = 15 students.

A rectangular prism has a base length of 6 units, base width of 5 units, and height of 4 units. The bases are shaded.
Angelina_Jolie [31]

Answer:

Part 1) The lateral area is LA=88\ units^2

Part 2) The area of the two bases together is 2B=60\ units^2

Part 3) The surface area is SA=148\ units^2

Step-by-step explanation:

Part 1) Find the lateral area

we know that

The lateral area of a prism is given by

LA=Ph

where

P is the perimeter of the base

h is the height of the prism

so

P=2(6+5)=22\ units ----> perimeter of rectangle

h=4\ units ---> given

substitute

LA=22(4)=88\ units^2

Part 2) The area of the two bases together is?

The area of the rectangular base B is equal to

B=(6)(5)=30\ units^2

therefore

The area of the two bases together is

2B=2(30)=60\ units^2

Part 3) The total surface area is

we know that

The surface area is equal to

SA=2B+LA

substitute

SA=60+88=148\ units^2

Can anyone help me with this
Nataliya [291]
To find surface area, we can use the equation:

SA=2lw+2wh+2lh, where:
l=10 in
w=3 in
h=7 in

SA=(2)(10)(3)+(2)(3)(7)+(2)(10)(7)
SA=60+42+140
SA=242 in²
