Answer:

= 100

Step-by-step explanation:

TSA of brick → 2(L×b+b×h+h×l)

= 2(22.5× 10 + 10 \times  7.5 +7.5 \times 22.5)

= 2 (225 +75 + 168.75) cm²

=2 ( 468.75) cm ²

= 937.5cm²

=  \frac{937.5 {cm}^{2} }{100 \times 100} =0.09375 m²

Therefore, Required number of Bricks-

=  \frac{9.375 {cm}^{2}  \times 100}{0.09375  \: {cm}^{2} }

= 100

  • Hence,The required Number of Bricks = 100 respectively.

Answer:

<h2>LA = 24 ft²</h2>

Step-by-step explanation:

In the base we have the right triangle. Use the Pythagorean theorem for to calculate the hypotenuse:

h^2=4^2+3^2\\\\h^2=16+9\\\\h^=25\to h=\sqrt{25}\\\\h=5\ ft

The Lateral Area is the sum of the areas of three rectangles:

4\ ft\ \times\ 2\ ft\to A_1=(4)(2)=8\ ft^2\\\\3\ ft\ \times\ 2\ ft\to A_2=(3)(2)=6\ ft^2\\\\5\ ft\ \times\ 2\ \ft\to A_3=(5)(2)=10\ ft^2

The Lateral Area:

LA=A_1+A_2+A_3\to LA=8+6+10=24\ ft^2
