Answer:
<em>3,750cm²</em>
Step-by-step explanation:
Total surface area of a cube is expressed as;
A = 6L²
L is the side length of the cube;
Given
L = 25cm
TSA = 6 (25)²
TSA = 6 * 625
TSA = 3,750cm²
<em>Hence the total surface area of the box is 3,750cm²</em>
Answer:
64\ units^{3}
Step-by-step explanation:
we have
V=s^{3}
This is the formula to calculate the volume of a cube
where
s is the length side of the cube
In this problem we have
s=4\ units
substitute
V=4^{3}=64\ units^{3}
Explanation:
We assume the problem statement is telling us that the order of points on segment QR is Q, A, B, R, and that QA = AB = BR. This means that
QB = QA +AB = 2BR
BR = 1/2(QB)
The area of the triangles will be ...
A = 1/2bh
For triangle PQB, the area is ...
ar(PQB) = 1/2(QB)h . . . . . h is the perpendicular distance from QR to P
For triangle PBR, the area is ...
ar(PBR) = 1/2(BR)h = 1/2(1/2QB)h . . . . h is the same as above
ar(PBR) = 1/2ar(PQB)

Essentially, you're showing the base of the smaller triangle is 1/2 the base of the larger one and using that to show the area of the smaller triangle is 1/2 the area of the larger one. (Both have the same height.)
It's the points of the triangle E----------G
They are the twin points
