The area of all 3 lateral triangular faces will be found by using the formula for area of a triangle.
A = 1/2bh
Face 1:
1/2 x 3 x 5
A = 7.5 square cm
Face 2:
1/2 x 4 x 5
A = 10 square cm
Face 1:
1/2 x 5 x 5
A = 12.5 square cm
12.5 + 7.5 + 10 = 30 square cm
The area of the lateral faces is 30 square cm.
V = ¹/₃Bh
V = ¹/₃(27)(15)
V = ¹/₃(405)
V = 135m³
The answer will be 0.4 just round 0.36 the 6 will go up making the 6 into a 0 and the 3 into a 4
The answer is A. You need an additional angle and the side must be between the two angles. It's called the 'included' side.
ASA means Angle, Side, Angle
