Answer:
21 square cm
Step-by-step explanation:
Answer:
1200 in²
Step-by-step explanation:
The surface area of the prism is the sum of the lateral area and the areas of the bases.
__
<h3>lateral area</h3>
The lateral area is the total area of the three rectangular faces. It can be computed from ...
LA = Ph
where P is the perimeter of the triangular base, and h is the height of the prism (the distance between triangular bases).
The perimeter is the sum of the edge lengths of the base:
P = 30 in + 17 in + 17 in = 64 in
Then the lateral area is ...
LA = (64 in)(15 in) = 960 in²
__
<h3>base area</h3>
The two bases are congruent triangles, so have a total area of ...
A = 2(1/2bh) = bh
where b is the base of the triangle, and h is its height.
A = (30 in)(8 in) = 240 in²
__
<h3>total surface area</h3>
The sum of lateral area and base area is ...
total area = (960 in²) +(240 in²) = 1200 in²
The surface area of the triangular prism is 1200 square inches.
Answer:
Should be 2, -5
Step-by-step explanation:
you flip –2, 5 along y axis, then get 2, 5
then flip 2, 5 along x axis and get 2, -5

<span>You are given two figures of 25 inch</span>² and 36 inch² surface areas respectively. Also, the smaller figure has a volume of 250 inch³. You are asked to find the volume of the larger area. To solve this, you can use ratio and proportion.
250 inch³/25 inch² = x/ 36 inch²
where x is the volume of the larger figure
x = 360 inch³
