What is the surface area of the prism?
Length 15 mm
Width 3
Height 4
A = 234?
A = 2L*h + 2L*W + 2W*h = 120 + 90 + 24 = 234 mm^2.
=
works for me
@Henry
what? Could you explain plz?
yeah
and I know this is almost a year old comment.
Oh oh oh oh oh oh I’m fallin’ so I’m takin’ my time on my ride
make that 4 years lol
To find the surface area of a prism, you need to calculate the sum of the areas of all its faces.
A prism typically has two congruent bases, which are identical polygons, and a certain number of rectangular faces connecting the bases. The formula for the surface area of a prism is:
Surface Area = 2(Area of Base) + (Perimeter of Base) × Height of Prism
In this case, the prism has a rectangular base with a length of 15 mm and a width of 3 mm, and a height of 4 mm.
To find the area of the base, you simply multiply the length by the width:
Area of Base = Length × Width = 15 mm × 3 mm = 45 mm²
The perimeter of the base is calculated by adding up the lengths of all four sides of the rectangle:
Perimeter of Base = 2(Length + Width) = 2(15 mm + 3 mm) = 2(18 mm) = 36 mm
Plugging these values into the surface area formula, we get:
Surface Area = 2(Area of Base) + (Perimeter of Base) × Height of Prism
Surface Area = 2(45 mm²) + (36 mm) × 4 mm
Surface Area = 90 mm² + 144 mm²
Surface Area = 234 mm²
So, the surface area of the prism is indeed 234 mm².
