Answer:
Step-by-step explanation:
Triangles
Area of a triangle = 1/2 b * slanted height
b = 6 m
h = 9 m
Area of 1 triangle = 1/2 * 6 * 9
Area of 1 triangle = 27
Area of all 4 triangles = 4*27 = 108 m^2
==================
Base area
The base is a square. All 4 sides are equal.
The formula for a square is s^2
Area = (6 m)^2
Area = 36 m^2
Total area
Total Area = 108 m^2 + 36 m ^2
Total Area = 144 m^2
If you add all of them together you will get 32
Attached below is the problem that I worked out. And I checked my answer simply by plugging it in
The surface area of the rectangular prism is 52 square feet (
), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Step-by-step explanation:
The given is,
A rectangular prism of
Let, h - height of the rectangular prism
w - Width of the rectangular prism
d - Depth of the rectangular prism
Step:1
From given,
h = 4 feet
w = 3 feet
d = 2 feet
Step:2
Formula to calculate the surface area of the rectangular prism is,

Substitute the values of w,d and h
= 2 [(3×2) + (4×2) + (4×3)]
= 2 (6+8+12)
= 2 × 26
= 52
A = 52 Square feet
Result:
Thus the surface area of the rectangular prism is 52 square feet (
), if the height is 4 feet, width is 3 feet and depth is 2 feet.
