Surface area means all 6 sides

TOP side= 2 multiplied by 5

Bottom = 2 multiplied by 5

Right face   = 2 multiplied by 8.1

Left face = 2 multiplied by 8.1

Back side = 5 multiplied by 8.1

front side = 5 multiplied by 8.1

10+10+16.2+16.2+40.5+40.5 = 133.4 cm ^2

Answer:

133.4 cm²

Step-by-step explanation:

The opposite faces of the cuboid are congruent, thus

front/ back = 2(8.1 × 5) = 2 × 40.5 = 81 cm²

top/ bottom = 2(5 × 2) = 2 × 10 = 20 cm²

sides = 2(8.1 × 2) = 2 × 16.2 =32.4 cm²

Thus

Surface area = 81 + 20 + 32.4 = 133.4 cm²

Which of the following angles is in the solution set of sec^2θ - 3secθ - 2 = 0 for 0° ≤ θ < 360°.
STALIN [3.7K]
1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O -  2 cos^2 O = 0

2 cos^2 O + 3 cos O - 1 = 0

cos O = 0.2807 , -1.78   ( -1.78 cannot be a solution)

O = 74 degrees  (from  0.2807) another solution is 360-74 =  286 degrees
