3 times. because 14x25=350 and 350 times 3 equals 1,050.
Each of the small 12 identical blocks has dimensions 4 by 5 by 7 inches.
Together they form a larger block of:
width w=5 in
length l = 7 in+7 in+7 in = 21 in
height h = 4 in + 4 in + 4 in + 4 in=16 in
The total area of the block is:
(front face+back face)+("floor" face + "ceiling" face) + 2 side faces
=
16 * 21 + 16*21 + 5*21+ 5*21 + 5*16+5*16 (square inches)
=
336+336+105+105+80+80 (square inches)
= 672+210+160 (square inches)
=1,042 square inches
Answer: 1,042 square inches
I find it useful to use a graphing calculator to find the zeros of higher-order polynomials. Once you find one or more rational zeros, you can factor them out to find the reduced polynomial factors (or you can use synthetic division).
1. This factors as (5x+2)(3x-1)(x-8). Roots are {-2/5, 1/3, 8}
2. This factors as (x-9)(x²-5x+2). Roots are {2.5-√4.25, 2.5+√4.25, 9}
3. This factors as (x-6)(5x²+3x+1). Roots are{-0.3-i√0.11, -0.3+i√0.11, 6}
